Exponent (now Aced) review: a deep tech prep library with free peer mocks and voice AI practice

What is Exponent, now called Aced?

Exponent, renamed Aced in 2026 and still at tryexponent.com, is a tech and finance interview prep membership from Exponent Labs, LLC in San Francisco, founded by Stephen Cognetta, a former Google product manager, and Jacob Simon. It bundles video courses for product management, software engineering, engineering management, data science, TPM and design roles, a database of candidate-reported interview questions, company guides, live peer mock interviews, a Slack community and job referrals. Newer additions are AI mock interviews and an AI coach called Ace on the top plan, AI grading of peer session transcripts for paying members, and an investment banking track. Human coaching is sold separately. Aced says it has served "over 1 million candidates and 40 top universities".

When did Exponent become Aced, and what happened to Pramp?

Exponent announced its new name on August 17, 2026, and Pramp, which Exponent bought in 2021, had already moved inside it in July 2024. The sequence, from the companies' own pages:

1. 2015: Pramp is founded as a free site where candidates interview each other.
2. November 18, 2021: Exponent acquires Pramp's assets, announced as "Pramp Joins Forces with Exponent". Pramp then reported more than 10,000 interviews a month.
3. July 2024: the pramp.com banner reads "As of July 2024, all new Pramp sessions are hosted on Exponent Practice. It's still free and even better."
4. August 17, 2026: the post "Exponent is becoming Aced" (updated August 31) describes Aced as "a family of brands that includes InterviewCake, Pramp, Resumes.fyi, APM List, and more."

In practice, little moved. The site is still tryexponent.com with the logo "Aced formerly Exponent", and the footer still names Exponent Labs, LLC. pramp.com is still online as a page branded "by Exponent", and every practice button on it leads to Aced's practice page, as the screenshot below shows. Expect search results, reviews and Reddit threads to use all three names for a while; they describe one product.

What did a free Aced account let us do?

A free Aced account got us to the practice page and into "Practice with AI" with no paywall, but its AI formats take voice only, so on September 18, 2026 we practiced no answer and saw no AI feedback. The steps below say exactly how far we got.

Signup

"Sign up for Aced" offered Google, Facebook, LinkedIn, "Log in with university", or an email and password. In our automated, headless test browser, submitting the email form twice returned "We couldn't verify your signup. Please try again." after a Cloudflare bot check. Following the retry rule we apply to every product, including our own, we tried again that evening in a regular desktop Chrome window with a fresh email address, and signup passed with no email verification step. Onboarding took five short screens: name, target role, what you need help with, target companies, and a "Get matched with job opportunities" screen whose recruiter visibility box came pre-ticked (we unticked it). We landed on the practice page as a Basic member, about 6 minutes and 8 screens after starting, at the pace of our slow form filling. We did not use social login, which our test rules exclude.

The practice page

The practice page reads "Practice mock interviews with peers and AI", with buttons to schedule a peer mock or start an AI interview, and lists upcoming live peer sessions by track. On the evening of September 18, 2026, the next Product Management session was "Today 10:00 PM" with 45 people joined; Data Structures and Algorithms showed 89 joined, System Design 85 and Behavioral 68. Logged out, clicking "Practice with AI" on a question card opened "Create an account to start practicing", with Google, Facebook and LinkedIn buttons and no email option in that window.

A public question page

The question "Tell me about a time when you handled a difficult stakeholder" was open to read without an account, with hints and 8 interview experiences shared by candidates, with companies such as Amazon and Google listed where it was asked. Detailed company statistics sat behind "Unlock detailed company stats for this question. Upgrade". Signed in, the same page adds a free text answer editor with "Practice with AI" and "Submit" buttons; we did not use Submit, which appears to post the answer to the community tab. For a candidate researching a behavioral round, this free layer is useful on its own.

Practice with AI on the free plan

On our Basic account, "Practice with AI" opened a setup window with a 10 minute limit for a behavioral question, a target role (Product Manager was preselected) and two formats: "Conversation, Simulate a realistic interview" and "Record, Record an answer and get feedback". No paywall appeared. In Conversation, the interviewer opened with a probing version of the question: "Can you describe a specific situation where you had to work with a difficult stakeholder?" There was no text box, and in Record the transcript box showed "Listening..." and did not accept typing. We do not grant a microphone in our tests, so we left without answering.

That leaves two of Aced's statements side by side. The pricing page lists AI mock interviews and AI interview feedback on Expert, and Aced's AI mock page reserves feedback and transcripts for paid members, while the practice page says "Skip the wait: answer real interview questions with instant AI feedback, any time" and the AI practice opened for us on Basic. We did not see what a free account gets after answering.

What we could not test

We did not hear the AI interviewer react to an answer, see its rubric feedback or time it, or learn whether the free plan caps AI sessions. We did not join a peer mock, open a course or book a coach, so we make no claim about their quality beyond what Aced and its users say.

What does each Aced plan include, and how do refunds and renewals work?

Exponent (Aced) costs $0 on Basic, $79 a month for Pro or $12 a month billed annually, and $99 a month for Expert or $20 billed annually, as of September 18, 2026, and refunds close 5 days after purchase. These are the plans on its pricing page:

• Basic, $0: sample lessons, 5 peer mocks a month, sample questions and basic job referrals, "no credit card required".
• Pro, $79 a month, or $12 a month billed annually: all courses, video and written solutions, company guides, real interview experiences, unlimited peer mocks, the full question database, priority referrals and the Slack community. The annual card carries a "SAVE 70%" label and the monthly card a "CRUNCH TIME" badge.
• Expert, $99 a month, or $20 a month billed annually: everything in Pro plus AI mock interviews, AI interview feedback and chat with the AI coach. (Our free Basic account could still open voice AI practice, as described above.)
• Coaching: sold separately from any membership, priced per coach, with packs of five sessions.

The page shows annual plans as a monthly rate only; by our arithmetic a year of Pro comes to $144 and a year of Expert to $240. For a single interview next week, that makes the free plan or one month the realistic choices, at $79 for Pro or $99 for Expert.

Aced's refund window is short: "We offer full refunds within 5 days of purchase." Memberships "renew automatically", and you cancel from your account page before the renewal date. Coaching has its own terms, and unused coaching sessions are refundable within six months.

What do Exponent users praise and complain about?

Exponent has little recent review data: on September 18, 2026 its Trustpilot page showed an average of 4.2 from 9 reviews, none in the previous 12 months, and we found no G2 listing for the interview prep product. The patterns across Trustpilot, Reddit and Blind:

• Peer practice is the most praised part. A May 2025 Trustpilot reviewer credits the peer network with connecting them to "supportive, intelligent tech professionals", and another says practicing with others eased nerves and helped them structure answers. On r/leetcode, one poster called free Pramp practice "highly effective" next to paid options.
• Partner quality varies. A Blind thread includes blunt complaints about peers who do not know how to ask questions, while others in the same discussion value simply getting used to the timer and talking out loud.
• Renewal charges. A November 2023 Trustpilot reviewer wrote: "Today I got a $200 charge out of the blue for an apparent 'auto renewal'. No warning, no email, no support."
• Content polish. Trustpilot feedback asks for clearer problem statements on some questions and easier navigation.
• Price for students. In an r/csMajors thread, a student looked for free mock interview options specifically to avoid paying for an Exponent subscription.

Is Exponent (Aced) worth it?

Exponent, now Aced, is worth paying for if you are preparing over weeks for a tech or product loop and will actually use the courses, question bank and unlimited peer mocks; a year of Pro on the annual plan, $144 by our arithmetic, costs less than one $179 human mock interview on interviewing.io. Engineers also get live coding and system design practice with a person in the peer mocks, and 5 of those a month cost nothing.

It is a weaker buy in three cases. If you mainly want an AI interviewer, Aced's AI mocks are a voice-only beta that uses one bank question per session and does not cover technical rounds, so try the free practice before paying for Expert. If your role is outside tech and finance, most of the catalog will not apply. And if your interview is in a few days, a monthly plan at $79 or $99 comes with a 5-day refund window and automatic renewal, so start on the free plan and upgrade only if the library clearly helps.

With an interview one to three days out, the free layer is the best use of Aced: read the public question pages for your role and target company, then book tonight's or tomorrow's peer session in your track and treat it as a dress rehearsal.

Which Exponent alternatives fit different needs?

Exponent bundles four things (courses, peer mocks, AI mocks and coaching), and each alternative below covers one of them in a different way. Prices below are as of September 18, 2026.

• interviewing.io: anonymous mock interviews with senior engineers from large tech companies at $179 per session, no subscription, and a full refund if you are unhappy, plus a free AI Interviewer for coding and system design. Read our interviewing.io review.
• Big Interview: 170 video lessons and a recorded practice simulator, free through many universities and workforce agencies, otherwise $39 for a 30-day subscription that renews, with a 30-day refund. Read our Big Interview review.
• Yoodli: an AI coach focused on how you speak (filler words, pace, conciseness), from $8 a month billed yearly, with 5 free roleplays and no refunds. Read our Yoodli review.
• Mock Interview Pro, our product: spoken mock interviews built from your job posting, company and round, from $39 once with a 14-day refund, but no coding environment, no human coach and no courses. See Mock Interview Pro vs Aced (formerly Exponent).

The longer list is on our Exponent alternatives page, and if cost is the deciding factor, our roundup of free interview practice covers the options that charge nothing.
