Best AI mock interview tools: 8 compared, led by the one that rehearses your actual interview
Mock Interview Pro team
We make Mock Interview Pro, which is one of the tools on this list. We placed it where we think it fits and say plainly when another tool is the better choice. How we test
For most candidates with a specific interview coming up, Mock Interview Pro is the pick: $39 once with a 14-day refund. It runs a live voice or video interview built from your posting and the company's rounds, and the debrief arrives in about a minute. For free follow-up practice, Yoodli gives 5 roleplays in total. For likely questions in seconds, Interviews by AI gives 3 free a month. For one-way video screens, use Huru. For big tech loops, use Aced's free peer mocks, then interviewing.io from $179 a session. Big Interview fits when a school pays, and ChatGPT Voice is free on any phone. Prices as of September 18, 2026.
Free: your company's interview rounds and a practice plan, before any payment.

What is an AI mock interview, and which tool fits your round?
An AI mock interview is a practice interview in which software asks the questions, listens to your spoken or typed answers and gives feedback afterward; the tools below differ most in whether the interviewer follows up and how fast and specific the feedback is. Start from the round you are facing and what you can spend this week. Prices are as of September 18, 2026.
- You have a specific interview coming up, at a named company, within weeks: Mock Interview Pro, a live voice interview for that company and round (video from the $59 pass), $39 once for 30 days and 3 voice mock interviews, with no renewal.
- You want to hear follow-up questions before paying anything: Yoodli, with 5 free roleplays built from your job description.
- You have almost no budget and want likely questions fast: Interviews by AI, 3 free questions a month, then $9.
- Your next step is a recorded one-way video screen: Huru, where you record and watch back; its delivery feedback sits on paid plans. For HireVue specifically, see HireVue practice tools.
- Big tech product or engineering loop: Aced for free peer mocks with a code editor, then interviewing.io if one senior engineer's verdict is worth $179 to you.
- You are a student or early in your career: ask your career center about Big Interview before paying for anything.
- You only have a phone: ChatGPT Voice works on iOS and Android; our interview practice apps page covers the mobile options in detail.
- You cannot spend anything at all: our free interview practice page ranks only the free options.
If you are preparing for a non-technical role, skip the tools built around coding banks and use one that writes questions from your posting (Mock Interview Pro, Yoodli, Interviews by AI or Huru). Typed practice on our public interview question pages is a free way to test answers before speaking them.
How did we choose and test these AI mock interview tools?
We included tools that let you answer interview questions and get feedback from software, are available today, and publish their prices, then put each one through the same test on September 18, 2026 where its free tier allowed it. The test is described in full on how we test: one candidate, a Senior Product Manager applying to a collaboration product, with the same three questions and the same two deliberately average answers on every tool. The answers are average on purpose, with vague ownership and no numbers, so a good tool should catch the gaps. We used free tiers only, an automated desktop browser and a simulated microphone, and we paid no competitor.
Four tools let us run the script on the free tier: Yoodli, Interviews by AI, Huru and Mock Interview Pro (on its free question pages). For Mock Interview Pro's paid voice and video interviews we used paid sessions our founder ran on the live product, plus timing across every completed session in the last 180 days; how we test describes that evidence and its limits. Aced blocked our automated browser at signup and then let us in from a regular Chrome window, but its free AI interviewer takes spoken answers only, so we practiced none there. Big Interview offers no free plan, and interviewing.io's AI covers only coding and system design. For those three we report what we could reach. ChatGPT is listed from OpenAI's documentation because a general assistant's result depends on the prompt a candidate writes.
We left out three groups on purpose:
- Live interview copilots. Final Round AI, LockedIn AI, Verve AI, ParakeetAI, Sensei AI and Beyz AI are built to suggest answers during the real interview, and several bundle a mock mode. They have their own page, AI interview copilots compared. Final Round AI's practice mode also sent us to a desktop app download in our test.
- Retired tools. Google Interview Warmup no longer works; its address now redirects to an article. See our Interview Warmup review and the Warmup alternatives.
- Human-only coaching. Coaches appear below where they are part of a product (Aced, interviewing.io), not as standalone picks.
Tools we have not covered yet include Revarta, Four-Leaf, Interview Sidekick and Skillora.
We make Mock Interview Pro and list it first, because it is the only pick here that researches the company's interview rounds and then runs a live interview for the round you choose. It shows its cons like every other pick, and no tool gets a score from us.
Which AI mock interviewers followed up, and how fast was the feedback?
Mock Interview Pro's voice interviewer and Yoodli followed up on what the candidate said, while Interviews by AI and Huru moved through fixed lists; those measurements separated the tools most clearly.
- Mock Interview Pro asked, in a paid voice session, about the candidate's specific role in the compliance system he had just described. Its debrief arrived 39 and 57 seconds after our paid sessions ended, with a median of 83 seconds across 608 completed sessions in the last 180 days, and typed feedback on its free question pages took 7.2 seconds.
- Yoodli asked three follow-ups tied to our story in about 2.5 minutes. Feedback took 13 seconds and about 24 seconds.
- Interviews by AI asked no follow-ups by design. Typed feedback arrived in about 4 seconds, the fastest we measured.
- Huru asked no follow-ups. Feedback on a recorded answer was waiting in the results page within 2 minutes 34 seconds; nothing appeared during the interview.
Scores are not comparable across tools. Yoodli scored our deliberately average answers 22% and 30%, partly because our looping audio could not answer follow-ups, while Mock Interview Pro's debrief scores competencies and gives a verdict instead of a number per answer. Read a score against the tool's own scale, and pay more attention to what the feedback tells you to change.
When is a human mock interviewer worth paying for instead of an AI one?
A human is worth paying for when you need judgment an AI interviewer cannot give: how a particular hiring committee will read you. An AI interviewer has no memory of what last quarter's candidates said, cannot vouch for you, and may be more generous or harsher than the person you will face. Candidates in threads like r/csMajors also say generic tools miss what they struggle with most: "The part I actually struggle with is the conversation itself".
Three cases stand out. Senior engineering candidates benefit from a calibrated verdict against a named company's bar, which is what interviewing.io sells. Anyone who freezes with real people should add at least one live session, and Aced's free peer mocks are a cheap way to get it. And if you need a coach to rethink your story, not just polish answers, an AI rewrite of a weak answer is not a substitute. Use AI for volume and a human for judgment.
Which AI mock interview tool can you start tonight for an interview this week?
With one to three days left, pick one tool and spend the time speaking, not comparing. With Mock Interview Pro's $39 1-Month Pass, run one voice mock interview for your exact round tonight, practice the one focus its debrief names, and run a second the day before; the pass is paid once with a 14-day refund. With no budget, use two of Yoodli's five free roleplays on your two most important stories, type your weakest answer into a free Mock Interview Pro question page for a rewrite, and say that version out loud twice. Avoid starting any subscription you would have to remember to cancel.
1. Mock Interview Pro (Our product)
Mock Interview Pro, which we make, is the AI mock interview tool that rehearses your actual interview instead of a generic one. You give it the job posting, the company and the round, and a live AI interviewer runs that interview by voice or on video, introducing itself with the company and role. In paid sessions on the live product, the voice interviewer followed up on the specific project the candidate had just described, and the video interviewer reacted to what it saw on camera. Every answer comes back with its weakest sentence highlighted, why it hurts, how to fix it and a rewritten version. The debrief then gives a plain verdict on whether the interview would advance you, a score for each competency with your own words cited as evidence, and one focus for the next session; video adds a presence score covering eye contact, composure and warmth. Across 608 completed sessions in the 180 days to September 19, 2026, the median wait for the debrief was 83 seconds. Pricing is paid once, as of September 18, 2026: $39 for 30 days and 3 voice interviews, or $59 for a year of unlimited voice interviews, 3 video sessions and the company research report, each with a 14-day refund and no renewal. Before paying, the free interview plan researches the company's interview rounds, and our interview question pages score typed answers.
What we observed
In paid sessions our founder ran on the live product, the video interviewer for an Amazon recruiter screen (July 29, 2026) opened by noticing "those guitars in the background", and the voice interviewer for an Airbnb screen (April 14, 2026) followed up with "what was your specific role in building that compliance system and those observability dashboards?" A weak line, "I'm a lead engineering at my current position", was highlighted and corrected. The debrief, verdict "This interview likely doesn't advance you" with a readiness score of 55, was ready 57 seconds after the call ended.
What works
- Questions are built from your job posting, company and interview round, and the free plan researches the company's rounds before you pay
- A live voice interviewer that asks follow-up questions on what you just said, and a video interviewer that reacts to what you say and what it sees
- Every answer gets its weakest sentence highlighted and rewritten, each competency is scored, and the debrief arrives in about a minute
- Video sessions score on-camera presence such as eye contact
- Pay once with no subscription or auto-renewal, and a 14-day refund
- Runs in any phone or laptop browser with nothing to install
What falls short
- No live coding environment, so coding rounds need another tool
Starting price: $39 one time. Free option: Typed practice answers with AI feedback on public question pages, plus a free interview plan; spoken mock interviews are paid. Prices checked September 18, 2026.
2. Yoodli
Yoodli was the only free AI interviewer on this list that followed up on our story in our shared test, three times in about 2.5 minutes, which is why this speech and roleplay coach from Yoodli, Inc. in Seattle ranks high on a list about mock interviews. You paste a job description, Yoodli builds a roleplay around the role, and the interviewer mixes preset questions with follow-ups based on what you said. Afterward you get rubric scores for STAR structure and active listening, coaching that quotes your own sentences, and analytics on filler words, pace and conciseness. The limits matter if you are preparing for one interview. The free Starter plan is 5 roleplays in total, not per month; Pro caps practice at 10 roleplays a week, and Yoodli does not offer refunds on cancellation. Starter and Pro recordings can be used for AI training, while Advanced excludes them. The product is built mainly for sales and enterprise training, and in our test it left the company field as "Not specified", so it will not prepare you for one employer's rounds. See the Yoodli alternatives if that is the gap you need filled.
What we observed
In our test on September 18, 2026, the AI interviewer asked three follow-up questions in about 2.5 minutes, each about our specific story, and said "I think I'm hearing the same story twice here." Feedback appeared 13 seconds and about 24 seconds after we clicked Save & View Analysis. Scores of 22% and 30% reflect our setup as much as the answers: our test audio looped one recording, so the candidate never answered a follow-up properly and the active listening rubric, which our looping audio could not pass, dragged both scores down.
What works
- Instant delivery analytics on pacing, filler words, conciseness and sentence starters
- Interview mode mixes preset questions with follow-ups based on what you said
- Free Starter plan needs no credit card, and paid plans start at $8 a month billed yearly
- Works beyond interviews, for presentations, pitches and hard conversations
What falls short
- Reviewers say it judges how you speak more than the substance of your answers
- No refunds on cancellation
- The free plan is 5 roleplays in total, and Pro caps practice at 10 roleplays a week
- No coding or system design interview practice
- Starter and Pro recordings can be used for AI training
Starting price: $8 a month billed yearly, or $11 month to month. Free option: Starter plan with up to 5 roleplays in total (lifetime), no credit card required. Prices checked September 18, 2026.
3. Interviews by AI
Interviews by AI was the fastest tool we measured: about 30 seconds from its homepage to a question written from our posting, and typed feedback with a sample answer in about 4 seconds. The web tool, made by Jake Rosenthal and Chloe Pappas, asks for no account, card or install for the first 3 questions, and it writes questions for any industry rather than pulling from a tech-only bank. That makes it a sensible first stop for a career switcher or early-career candidate who mainly wants to know what the posting implies they will be asked. It is not a mock interview in the conversational sense: questions come one at a time, nothing follows up, and there is no score, delivery analysis or video. The free plan resets to 3 questions each month and Pro removes the cap. No refund policy is published, though canceling keeps access to the end of the paid period, and after question 3 Google is the only sign-in option. The site says audio recordings are deleted right after transcription. Our side-by-side with Mock Interview Pro covers the two in more depth.
What we observed
In our test on September 18, 2026, three clicks and about 30 seconds took us from the homepage to a first question generated from our job description. Typed answers got a feedback paragraph and a sample response in about 4 seconds. The feedback caught missing metrics, but it once flagged a hedging phrase ("I think") that our answer did not contain, and it praised the clarity of a failed two word transcript. Question 4 required Google sign-in.
What works
- Generates role-specific questions from any pasted job description, for any industry
- Written feedback plus a sample response on every question, returned about 4 seconds after a typed answer in our test
- No account, card or install needed for the first 3 questions; you can speak or type each answer
- Free plan with 3 questions a month and no card, and Pro costs $9 a month
- Audio recordings are deleted right after transcription
What falls short
- One question at a time with no follow-up questions, so it does not feel like a real interview
- No video, delivery or body language feedback
- The free plan allows only 3 questions a month, and resume-based feedback is Pro only
- No refund policy is published
- A reviewer found the answer time limit too short
- No score and no visible STAR breakdown in our test, and feedback praised clarity on a failed two word transcript
Starting price: $9 a month, month to month. Free option: Basic plan with 3 practice questions a month, audio or text answers and instant feedback, no card required. Prices checked September 18, 2026.
4. Huru
Huru, the video practice app from Beatview, Inc., is the pick here that feels most like a recorded one-way screen: a question appears, you record on camera against a time cap (2 minutes on the question we saw), and you watch yourself back. It builds practice interviews from job listings or a 50,000 question library, and Huru says its feedback covers your answers, voice and facial expressions. A tips panel beside each question explains what the interviewer is looking for, and paid plans add grammar, confidence and model-answer tabs. It also has an iPhone and iPad app, a Chrome extension that turns a listing on a job board into a mock interview, and practice in five languages. It does not converse: questions come from a fixed list with no follow-ups. Both paid plans have the same features, and every payment, including renewals, is non-refundable. The free trial is small, as our test found, and the Android app is gone from Google Play. If your screen is on HireVue specifically, our HireVue practice tools page goes further.
What we observed
In our test on September 18, 2026, the first question built from our job description was on screen about 110 seconds after we landed on the homepage, with no card. Huru moved to the next question after each answer with no follow-up. Feedback on answer 1 was waiting within 2 minutes 34 seconds, but the free view showed only an Accuracy paragraph that paraphrased the answer, with no score. After 2 recorded answers the trial disabled practice and results without warning.
What works
- Chrome extension turns a job listing on any website into a mock interview
- Delivery feedback covers pace, pauses, filler words and facial expressions
- Watching recorded answers back suits one-way video screen practice
- Available in five languages and on iOS as well as the web
- Annual plan works out to $8.25 a month
- Fast start in our test, about 110 seconds from the homepage to a first question built from a pasted job description, with no card
- A tips panel next to each question explains what the interviewer is looking for and suggests an answer framework
What falls short
- Every subscription payment is non-refundable, including renewals
- Recorded answers to set questions, with no follow-up questions
- A 2025 Trustpilot reviewer said a paid mock interview failed to ask any questions
- No Android app, since the Google Play listing is gone
- No company research or round-specific preparation
- In our test the free trial stopped after 2 recorded answers, and free feedback was limited to one paraphrasing Accuracy tab
Starting price: $24.99 a month, or $99 a year billed upfront. Free option: Free trial with no card; in our test it disabled practice and results after 2 recorded answers, with no warning beforehand. Prices checked September 18, 2026.
5. Aced (formerly Exponent)
Aced, the tech and finance prep membership from Exponent Labs, LLC that was called Exponent until its rename, is on an AI list less for its AI interviewer than for the live practice around it. The free Basic plan gives 5 live peer mock interviews a month with a shared code editor, through the peer network that was Pramp, so product, engineering and data candidates can rehearse with a person, including coding and system design rounds. The AI mock interviews are a beta on the Expert plan: audio sessions of 10 to 20 minutes on one bank question, with no technical interviews or live coding. Questions come from the bank rather than your posting, and there is no body language feedback. Expert, the plan that includes the AI interviewer, costs $99 a month or $20 a month billed yearly, as of September 18, 2026. Memberships renew automatically and refunds are limited to 5 days after purchase. Courses, a question database and paid human coaching round out the membership. If you already use Aced and want something else, see Exponent alternatives.
What we observed
On September 18, 2026 a human check ("We couldn't verify your signup. Please try again.") stopped our automated test browser at email signup, and our own site's check failed in the same browser. On a second try in a regular Chrome window the signup worked, and about 6 minutes and 8 screens later we had a free Basic account and a free AI interviewer. It accepts only spoken answers, so we practiced no answer. The pricing page lists AI mock interviews and AI feedback only on Expert. We did not test a peer mock.
What works
- Free Basic plan includes 5 live peer mock interviews a month with no credit card
- Deep course library and candidate-reported question database for PM, engineering, data science and system design
- Peer mocks include a collaborative code editor, so coding and system design rounds can be practiced with a human
- Human coaches are available when you want feedback from someone experienced
- Annual billing brings Pro to $12 a month
What falls short
- Monthly prices are high at $79 for Pro and $99 for Expert
- Refunds only within 5 days of purchase, and memberships renew automatically
- AI mock interviews are a voice-only beta that uses one bank question per session and skips technical rounds; the pricing page lists AI mocks and AI feedback on Expert
- Questions come from the bank rather than your specific job posting, and there is no body language feedback
- Peer partner quality varies, according to users on Blind
Starting price: $12 a month billed yearly (Pro). Free option: Basic plan with 5 peer mocks a month, sample lessons and questions, no card; voice Practice with AI opened on a Basic account in our test. Prices checked September 18, 2026.
6. interviewing.io
interviewing.io, the San Francisco marketplace from Interviewing.io Inc., sells what no AI tool on this list can: an anonymous mock interview with a Senior, Staff or Principal engineer who has run 20 or more real interviews and tells you where you stand against their company's bar. You can request an interviewer from a specific company such as Google, Meta or Stripe, at a higher price. Human sessions start at $179 each with no subscription, and the FAQ promises a full refund if you are unhappy with an interview. Its free AI Interviewer covers coding and system design with 200+ problems, and $20 a month saves those sessions for review, as of September 18, 2026. The AI side is narrow: no behavioral, product or non-engineering practice, and sessions are audio and chat with no video. For a software engineer, a sensible plan is free AI reps first, then one paid human mock before the real loop. Candidates weighing other options can compare them on our interviewing.io alternatives page.
What we observed
In our test on September 18, 2026, the free AI Interviewer offered only coding and system design interviews, so our product manager questions could not be practiced. Onboarding asked for a LinkedIn profile before setup could be finished. The default booking, a Senior+ algorithms mock with a professional interviewer, showed $189 and the full refund promise.
What works
- Real senior engineers from FAANG and similar companies give calibrated feedback against that bar
- You can request an interviewer from a specific company
- Free AI Interviewer covers coding and system design with 200+ problems
- Human sessions are paid per session with no subscription, and the FAQ promises a full refund if you are unhappy with an interview
- Public library of recorded mock interviews to learn from
What falls short
- Human sessions start at $179 each, and company-specific interviewers cost more
- Built for engineering roles, with nothing for sales, marketing, operations or finance interviews
- The free AI Interviewer covers only coding and system design, with no behavioral practice
- In our test, onboarding asked for a LinkedIn profile before the booking form could be used
- Audio only, so there is no video or body language feedback
- Users on Blind report that interviewer quality varies
- Dedicated coaching package prices are not published on the site
Starting price: $179 per human mock interview, paid per session. Free option: Free AI Interviewer for coding and system design, and free peer-to-peer mocks (quality not guaranteed); login required, no card needed. Prices checked September 18, 2026.
7. Big Interview
Big Interview, from Skillful Communications and its co-founder, career coach Pamela Skillings, is the course among these picks: 170 video lessons teach answer structure before its recorded practice simulator asks you anything. A question library filters by industry, role and seniority, and PracticeAI runs voice-only mock interviews that its site says are personalized from a resume or job description. According to Big Interview, the AI feedback covers delivery, pace, filler words, eye contact and body language as well as answer quality. Many universities and workforce agencies provide it free, so check your career center before buying. Individuals get no free plan. Interview BootCamp costs $39 for a 30-day subscription that renews until canceled, and Interview Accelerator, $99 for 3 months, also renews; Interview Pro is $299 once for lifetime access, as of September 18, 2026. Its 100% refund within 30 days if you do not see results is longer than most memberships here. Its feature pages do not say the interviewer asks follow-ups, and reviewers find the course introductory for experienced candidates.
What we observed
On September 18, 2026 we created an account as an individual buyer, and the next screen offered only the three paid plans, each billed that day, with no free or trial option. We stopped without paying, so we could not test a lesson, PracticeAI or its feedback.
What works
- A structured curriculum of 170 video lessons that teaches answer structure from scratch
- Large question library filtered by industry, role and seniority
- AI feedback covers delivery, pace, filler words, eye contact and body language as well as answer quality
- A $299 lifetime option and a 30 day no questions asked refund
- Many universities and workforce agencies provide it free to their members
What falls short
- Its feature pages do not say the practice interviewer asks follow-up questions, and nothing can be tried before paying
- PracticeAI says it personalizes questions from a resume or job description, but nothing we found builds practice around one company's interview rounds
- No free plan for individuals, and the $39 and $99 plans renew until cancelled
- Reviewers find the curriculum introductory for experienced candidates
- No coding or system design practice environment
Starting price: $39 for a 30-day subscription that renews. Free option: No free plan for individuals; free access comes through partner universities and agencies, plus a free email course. Prices checked September 18, 2026.
8. ChatGPT
ChatGPT, OpenAI's general assistant, earns a place because its Voice mode can play a demanding interviewer on the phone you already carry, and the free plan includes some voice use. It is a legitimate option. Paste the posting, ask it to act as an interviewer who asks one question at a time and follows up, and it will hold a natural back and forth, with the transcript saved to the chat for review. The free plan has no published voice cap, and Plus costs $20 a month with 3 hours of Live voice per rolling 24 hours, as of September 18, 2026. What you give up is structure. OpenAI documents no interview mode, rubric or score history, so the session is only as good as your prompt. It can be kinder than a real interviewer unless you ask for critical feedback, and OpenAI says voice transcripts are not verbatim, so feedback on exact wording can drift. We did not run ChatGPT through our script, because a general assistant's result depends on the prompt a candidate writes; this entry is based on OpenAI's own documentation.
What works
- A legitimate free option for spoken practice, with limited voice access on the free plan
- Works on the web as well as the iOS and Android apps
- You can paste a job description and ask for questions tailored to it, and ask for a tougher interviewer
- Natural turn taking in Live voice, with the transcript saved to the chat for review
What falls short
- No structured interview scoring, rubric or score history across sessions
- Results depend on how well you write the interviewer prompt
- Can be more encouraging than a real interviewer unless you ask for critical feedback
- Transcripts are not verbatim, so feedback on exact wording can be off
- No timed one-way format for HireVue-style rehearsal
Starting price: $20 a month for Plus, billed monthly. Free option: Limited voice access on the free plan; OpenAI publishes no fixed limit. Prices checked September 18, 2026.
Questions people ask
Is there an AI mock interview tool that is completely free?
Not with unlimited spoken practice, as of September 18, 2026. Yoodli's free plan is 5 roleplays in total, Interviews by AI gives 3 questions a month, Aced gives 5 peer mocks a month, and interviewing.io's AI Interviewer is free for coding and system design only. ChatGPT and Gemini offer limited free voice use. Mock Interview Pro's free options are the interview plan and typed practice on its question pages. Every free option is compared in free interview practice.
Do AI mock interviewers ask follow-up questions?
Some do. In a paid voice session on April 14, 2026, Mock Interview Pro's interviewer asked about the candidate's specific role in the system he had just described. In our free test on September 18, 2026, Yoodli asked three follow-ups specific to our answer in about 2.5 minutes. Interviews by AI and Huru never did; they move through a fixed list. Big Interview's paid interviewer could not be tested without paying.
Do AI mock interviews actually help?
They help with the part candidates tend to skip: saying answers out loud and hearing where they are vague or run long. We did not measure whether any tool raises your odds of an offer, and no vendor on this page publishes that. Use AI practice for repetitions and specific fixes, and judge a tool by whether its feedback names a concrete change to your answer, not by the size of its score.
Which AI mock interview tools give feedback on body language?
Mock Interview Pro's video sessions do: in a paid session on July 29, 2026, the debrief gave a presence score of 78 across 20 dimensions such as eye contact, composure and facial warmth, and named two things to improve. Video needs the $59 1-Year or $249 Lifetime Pass. Huru says it gives feedback on facial expressions, Big Interview says its AI feedback covers eye contact and body language, and Yoodli reports eye contact too; our shared test camera showed a test pattern, so we could not judge those.
Are my practice recordings used to train AI?
It depends on the plan. Yoodli says Starter and Pro roleplay data can be used for AI training, while Advanced ($20 a month billed yearly) excludes it. Interviews by AI says audio is deleted right after transcription. OpenAI keeps ChatGPT voice clips with the chat for 30 days and trains on audio only if you opt in. Check each tool's privacy page before recording.
How we tested
On September 18, 2026 we ran the shared Senior Product Manager script (three questions, two deliberately average answers) on each tool's free tier where it allowed practice, in an automated desktop browser with a simulated microphone and camera, without paying, and recorded prices and refund terms from each vendor's pages that day. Yoodli, Interviews by AI, Huru and Mock Interview Pro (its free question pages) let us practice. Mock Interview Pro's paid voice and video interviews are described from paid sessions our founder ran on the live product, detailed on how we test. Aced's signup blocked our automated browser with a human check; a regular Chrome window got us into its free AI interviewer, which is voice only, so we practiced no answer. Big Interview offered only paid plans, and interviewing.io's AI Interviewer covers coding and system design only. ChatGPT was not run through the script; its entry relies on OpenAI's documentation.
