Mock Interview Pro vs Exponent (now Aced): tech prep membership or practice for one job

Is Exponent now Aced, and is Pramp part of it?

Yes: Exponent renamed itself Aced in August 2026 and still runs on tryexponent.com, and Pramp's free peer interviews have run inside it since July 2024. So whether you searched for Exponent, Aced or Pramp, this page compares the same membership with Mock Interview Pro; our Exponent review covers the rename and old Pramp accounts.

Which one covers a big tech PM or engineering loop better?

Aced covers a big tech product management, software engineering, system design or data science loop far better than Mock Interview Pro does. Its Pro plan unlocks courses for PM, engineering, engineering management, data science and TPM roles, video and written solutions, company-specific guides, a database of candidate-reported questions and what Aced describes as "350+ hours" of expert video answers. Its peer mocks pair you with another candidate for about 30 minutes each way over live video, with a shared code editor for Python, Java, C++ and other languages, in tracks from Data Structures and Algorithms to System Design, SQL and Frontend. If you want someone experienced to watch you, Aced sells 1:1 sessions with vetted coaches separately.

Mock Interview Pro has none of that: no courses, no live coding editor, no human coach and no community. For a coding or system design round, a human partner in Aced's code editor is the better rehearsal. Where Mock Interview Pro fits is the spoken part of a loop (behavioral, hiring manager and experience questions) and roles outside the tech and finance tracks Aced is built around.

The public Aced question page we opened shows what the question bank adds. "Tell me about a time when you handled a difficult stakeholder" came with hints, interview experiences shared by candidates at named companies, and an upgrade prompt to "Unlock detailed company stats for this question."

Who asks the questions: a peer, Aced's AI or an interviewer built from your posting?

On Aced, a fellow candidate asks the questions in a peer mock, or its AI interviewer asks one bank question per session; on Mock Interview Pro, an AI interviewer asks questions built from the job posting, company and round you enter.

Aced's AI mock interviews are voice sessions of 10 to 20 minutes on an automatically assigned popular question you can shuffle, scored per competency against what Aced calls "hiring rubrics". Aced labels them beta and says they do not support technical interviews or live coding. When we reached the free Basic plan in a regular Chrome window on September 18, 2026, "Practice with AI" offered a Conversation format and a Record format, and in Conversation the interviewer opened by asking for a specific situation and what made the stakeholder difficult. Both formats take voice only, so we did not answer and cannot say how it scores.

Peer mocks run on a schedule rather than on demand: on the evening of our test, the next Product Management session was listed for "Today 10:00 PM", with 45 people joined. The quality of the person across from you also varies, a complaint in a Blind thread about Pramp, though users there also credit it with getting them used to the timer and to talking out loud.

Mock Interview Pro starts from your target job instead of a bank. In our test, its free interview plan listed seven interview rounds for a product manager role at Atlassian, citing "15 sources", before asking for any money. A paid session is a voice interview in the browser for the round you pick, and Mock Interview Pro says every answer comes back with a score, one prioritized fix and a rewrite; on the $39 pass the paywall labels this "Basic AI feedback". It also says its interviewer asks follow-ups based on your answers, which our free test could not reach. Aced's questions are ones candidates report from actual loops, while Mock Interview Pro's are built for your posting rather than collected from past interviews.

Are Exponent's 5 free peer mocks worth more than Mock Interview Pro's free plan?

For live practice, yes: Exponent's free Basic plan includes 5 peer mocks a month with a real person, while Mock Interview Pro's free options are its interview plan and typed answers with AI feedback. Aced's Basic plan also adds sample lessons and sample questions, with no credit card. Mock Interview Pro's free interview plan takes about 20 screens and an email and returns your company's interview rounds with sources and a practice plan, and its public interview question pages score typed answers for free. Speaking to its interviewer needs a pass.

Whether a free Aced account gets AI feedback is still open. In our test, voice AI practice opened on Basic with no paywall, while Aced's pricing page lists AI mock interviews and AI interview feedback on Expert; our Exponent review sets out exactly what we saw on each page.

What does one interview cost on Aced compared with Mock Interview Pro?

For one interview, Aced costs between $0 and $99 depending on whether peer mocks are enough, and Mock Interview Pro costs $39 once; both at list prices on September 18, 2026. Here is the arithmetic by prep window.

• One interview within a week. Mock Interview Pro: the 1-Month Pass at $39 gives 30 days and 3 voice mock interviews, without video or the full company research report. Aced: $0 if the free 5 peer mocks and sample content cover you and a slot fits your week; $79 for a month of Pro to get unlimited peer mocks, all courses and the full question database; $99 for a month of Expert, the plan whose card lists AI mock interviews and AI feedback. Monthly Aced plans renew automatically.
• One month with several interviews. Mock Interview Pro: still $39, or $59 once for the 1-Year Pass with unlimited voice mock interviews, 3 video sessions and the company research report. Aced: $79 or $99 for the month, or an annual plan.
• Months of searching. Aced's annual plans are its cheapest rate: Pro at $12 a month and Expert at $20 a month, billed annually. The pricing page shows only the monthly figure; by our arithmetic that is $144 and $240 for the year, and the membership renews. Mock Interview Pro's 1-Year Pass is $59 once for 365 days.

The terms differ more than the prices. Aced says "We offer full refunds within 5 days of purchase" and that memberships renew automatically unless you cancel before the renewal date from your account page; one 2023 Trustpilot review describes a $200 renewal charge with "No warning, no email, no support." Mock Interview Pro's passes do not renew and come with a 14-day refund. Aced coaching is a separate purchase, with unused sessions refundable within six months.

Coding round or behavioral round in two days: Exponent's free peer mock or Mock Interview Pro?

With two days left, choose by round type. For a coding or system design round, sign up for Aced's free plan and book the next peer session in that track, because working a problem out loud in a shared editor with a person is the closest rehearsal you can get for free. For a behavioral or hiring manager round tied to one posting, Mock Interview Pro's $39 pass lets you run a voice mock tonight, fix the weakest answer and run it again tomorrow; Aced's free voice practice is another option to try first, though we could not see what feedback it returns. Whichever you pick, spend tonight saying answers out loud rather than rereading notes, so the first time you say them is not in front of the interviewer.
