Someone looking for a Pramp mock interview today lands on a site that still has Pramp's name on it and a notice near the top explaining that the product moved. Pramp's own page states that as of July 2024, all new Pramp sessions are hosted on Exponent Practice. That destination has since been renamed again.
The format itself survived both moves intact, and it is worth understanding on its own terms, separately from the branding. Peer mock interviewing is two strangers taking turns interviewing each other over video, with the platform supplying the pairing and the questions. That idea has now outlasted two owners and two names. What has changed is which parts of it are automated, which of those parts cost money, and the arithmetic of what an hour of it buys you.
Key takeaways
- Pramp's peer sessions moved to Exponent Practice in July 2024, and Aced's practice page now states that Pramp is now Aced (formerly Exponent). Reaching them runs through an Aced account.
- A session is reciprocal. Aced's practice page puts it at approximately 30 minutes each, making the entire session about an hour long, so half the hour is you interviewing somebody else.
- Peer practice and your partner's written feedback are still free, now metered by monthly credits. The automated transcript and AI grading, which Pramp never offered, need a paid membership.
- Sessions run at published times per track. Aced lists Finance at 8 AM Pacific Time on Sundays and Wednesdays, the only one of its eight tracks scheduled less often than daily.
- Both peer practice and an AI interviewer are rehearsal, and neither is connected to the hiring decision.
What actually happened to Pramp?
Pramp was folded into Exponent, and Exponent has since rebranded to Aced. The evidence for each step is on the companies' own pages. Pramp's site carries the July 2024 notice quoted above and points its calls to action at the new destination. Aced's practice page answers the question directly for returning users, stating that Pramp is now Aced (formerly Exponent) and that you can schedule the same types of mock interviews on Aced as you could on Pramp, however you'll need an Aced account.
Two brand changes in roughly two years is disorienting, and it explains why search traffic for the old name has not gone anywhere. The practical answer for a candidate is short. The peer mock interview product still exists, it works roughly the way it used to, and reaching it means going through an account under a name you were not looking for.
One detail has drifted in the meantime, and it matters because candidates plan around it. Pramp's page describes a session where you and your peer will interview each other for 30-45 minutes. Aced's current practice page describes approximately 30 minutes each, making the entire session about an hour long. The Pramp-branded page predates the move and describes an older shape of the product, so anything it says about how sessions run should be treated as history and checked against Aced's page before you plan a week around it.
What does a peer mock interview do well?
It puts a live human on the other side of the table, and that is not a small thing. A peer can interrupt, look confused, follow up on the vague part of an answer, and run out of patience. Those reactions are the pressure that solo rehearsal cannot manufacture, and Four-Leaf's guide to practicing alone is candid that this is exactly where solo methods stop.
The reciprocity that costs you the extra half hour is also the format's best idea. Sitting in the interviewer's chair for thirty minutes teaches you what a rambling answer feels like to listen to, which is the fastest way to stop giving them. Aced's practice page states that interviewer and interviewee roles are randomly assigned at the start of the interview, and you switch halfway through, so the second seat is built into the format.
The pairing is deliberate and the technical tracks are real. Aced's page describes a matching algorithm that considers your schedule and availability, current role, experience level, and interviewing history, which is what separates a useful session from a random one. For Data Structures and Algorithms, SQL and Frontend interviews, Aced states that your peer will be preassigned a coding question to ask you, and those sessions run in a shared code editor. Candidates preparing for coding loops will find Four-Leaf's roundup of coding interview prep tools covers how peer practice fits alongside raw problem volume.
What does a free peer session actually ask of you?
Three things, and none of them appears on a pricing page.
The first is time at a ratio most candidates do not budget for. An hour of calendar time buys roughly thirty minutes of you answering questions, because the other half is service to your partner. That trade is fair and it is still a trade. Three sessions a week is three hours.
The second is scheduling. Aced's practice page publishes a fixed daily timetable. Product Management, Behavioral and System Design each run at 2 AM, 8 AM, 12 PM, and 6 PM Pacific Time, and Data Structures and Algorithms runs every two hours between 8 AM and midnight, local time. For most tracks the next session is within a day. The exception is worth knowing before you rely on it: Aced lists Finance at 8 AM Pacific Time on Sundays and Wednesdays, so a finance candidate invited on Tuesday for Thursday morning may find the next session lands after the interview does.
The third is that the automated record costs money, though it is not a record Pramp ever provided. Your partner's feedback is part of the free session, and Aced's page describes trading detailed notes with your partner using realistic rubrics after the session ends. What sits behind membership is the machine layer on top of that. Aced scopes it to four of its eight tracks, stating that for Behavioral, Product Management, System Design, and Data Science & ML interviews, you'll receive an automatic transcript of your interview, graded according to realistic hiring rubrics, and that to unlock feedback and transcripts, you'll need to upgrade to a paid membership. Aced calls the feature early access. Someone rehearsing data structures and algorithms sits outside that list whether or not they pay. A free session leaves you with your partner's written notes.
There is a fourth constraint worth naming because it is absolute. Aced's page states that we don't support mock interviewing on mobile devices. Peer practice happens at a desk or not at all.
How does peer practice compare with an AI mock interview?
The two formats fail in opposite directions, which is why a ranking would be the wrong shape here. A peer gives you unpredictability and costs you scheduling. An AI interviewer gives you availability and costs you the surprise of a real person.
| Dimension | Aced peer mock interview | Four-Leaf voice mock interview |
|---|---|---|
| Who asks | Another candidate, matched on schedule, current role, experience level and interviewing history | An AI interviewer that builds follow-ups from your spoken answer |
| When you can start | Published daily session times per track | Whenever you open it |
| Cost in time for 30 minutes of your own reps | About an hour, because the session is reciprocal | About 30 minutes |
| What you keep afterwards | Your partner's written notes; automatic transcripts and AI grading need a paid membership, on four of the eight tracks | One debrief at the end, scoring each completed question on relevance, specificity, structure, role fit and communication |
| Role coverage | Eight peer tracks, three of them labelled beta, covering tech plus finance | 23 named role tracks plus a general fallback |
| Price | Per Four-Leaf's pricing record, $79 a month for Pro or $149 charged yearly, with AI mock interviews needing the Expert tier at $99 a month | $20 a month, or $5 for a five day pass, after a 3-day free trial |
| Can it tell you whether you passed | No | No |
That last row is the one to read twice, because it is identical for both and no tool on either side of the comparison can change it. A rubric score and a peer's encouragement are both rehearsal signals. Neither has any connection to the hiring decision, and any product that implies otherwise is selling something. Four-Leaf's own roundup of mock interview platforms compares eight of them on price and format.
The price row needs a caveat stated plainly. The Aced figures come from Four-Leaf's competitor pricing record, verified on 16 September 2026 against the vendor's upgrade page, and the annual route is the one to compare against for a search that runs months. Aced's current pricing page renders its plans in JavaScript that a plain fetch cannot read, so anyone deciding on price should open it themselves rather than trust a number from anybody's comparison table, including this one.
What is overrated
The word free, applied to Aced's peer sessions, does most of the misleading here. Those sessions genuinely cost nothing in money, and for a job seeker two weeks out from an interview the scarce resources are hours and calendar control. A format that takes an hour of scheduled time to deliver thirty minutes of practice is priced in the currency that is actually tight, whatever the sticker says.
Also overrated is the instinct to pick one. Aced's peer sessions and Four-Leaf's voice mock interviews are complements. Repetition is cheap and available on demand on one side; genuine human unpredictability lives on the other, and the two costs do not overlap.
A practical week
- Check Aced's timetable for your track first, because that is the constraint you do not control. If your track is Finance, or the next slot falls after your interview, the rest of the week plans itself around that.
- Book the peer sessions that actually exist this week, and save them for answers you have already rehearsed, so the human on the other side spends their thirty minutes on the parts only a human can catch.
- Use on-demand voice practice for volume: the first pass at a new answer, the reps that make it shorter, the reruns after you rewrite it.
- Take the interviewer seat seriously. It is half of what the session costs you, and listening to someone else ramble is the fastest cure for your own rambling.
- Write your own notes within ten minutes of every session, whatever record the platform does or does not hand you.
- Treat the beta tracks with appropriate suspicion. Aced labels SQL, Data Science and ML, and Frontend as beta, which is the company telling you those sessions are less settled than the rest.
Where this is heading
The Pramp story is a small lesson in how candidate tools work. A format that candidates valued got acquired, renamed twice, and now meters access by monthly credit, with a newer automated layer sold separately on top of it. That is the ordinary lifecycle of a free product with real costs behind it.
What it leaves the reader holding is the same work it always was. Somebody has to say the answer out loud, hear how long it actually runs, notice the place where it goes vague, and say it again shorter. Peer sessions can carry part of that, an AI interviewer can carry more of the repetition, and neither one does the part where you decide what the answer should have been. That part has not been acquired by anyone yet.
