Pramp vs interviewing.io is a choice between free practice with peers and paid practice with experts. Pramp, whose sessions now run on Aced Practice, matches you with another candidate for a free session of about an hour in which you take turns interviewing each other, while interviewing.io books you an anonymous mock interview with a senior, staff or principal engineer, starting at $179 per session. Use Pramp for frequent, low-stakes reps and interviewing.io for a few expert sessions before an important onsite. Details are as of October 2026.
We make CoPilot Interview, a different practice tool, and cover it as a third option near the end. Pramp and Aced facts come from pramp.com and Aced's practice FAQ and pricing page; interviewing.io facts come from its homepage and FAQ. All were read on October 20, 2026.
First: what happened to Pramp
Pramp still has a homepage, but a banner on pramp.com says that as of July 2024, "all new Pramp sessions are hosted on Aced Practice." Aced is the new name of Exponent (its pages read "Aced (formerly Exponent)," run by Exponent Labs, LLC). The Aced Practice FAQ says you can schedule the same types of mock interviews you could on Pramp, but you need an Aced account, and you can link an old Pramp account to it. In this guide, "Pramp" means the peer mock interviews now on Aced Practice. For the rest of Aced's product, see our Exponent (Aced) review.
The verdict: which to pick
- Pick Pramp (Aced Practice) if you want many reps at no cost, you're early or midway through prep, you want to practice on video, or you prepare for product, behavioral or finance rounds as well as coding.
- Pick interviewing.io if you have a big-tech onsite within a few weeks, you want feedback from someone who runs those interviews, you're interviewing at senior, staff or manager level, and you can spend $179 or more per session.
- Use both if you can: free peer mocks for volume, then one or two expert sessions in the final weeks for a realistic read on where you stand.

What a month of practice costs
Our arithmetic from the listed prices, before tax and before any company-specific premium on interviewing.io:
| Practice plan for one month | Pramp (Aced Practice) | interviewing.io |
|---|---|---|
| 4 mock interviews | $0 (within Basic's 5) | From $716 |
| 10 mock interviews | $79 (one month of Aced Pro) | From $1,790 |
| 5 peer mocks plus 2 expert sessions | $0 for the 5 peer mocks (Basic) | From $358 for the 2 expert sessions |
The last row, from $358 in total, is the mix most candidates can afford: free volume with peers, and expert time only where it changes your preparation.
How a session works on each
A Pramp session on Aced Practice
- Pick a topic and a slot. Coding sessions start every two hours from 8 AM to midnight in your local time; product, system design and behavioral sessions start at 2 AM, 8 AM, 12 PM and 6 PM Pacific Time.
- Get matched. Aced pairs you based on your schedule, current role, experience level and interviewing history.
- Interview each other. Roles are assigned at random and you switch halfway, about 30 minutes each, over a video call that stays open for up to two hours.
- Code together where it applies. Coding sessions support Python, JavaScript, Java, Go, C++, C, C#, Ruby and Swift; SQL sessions use PostgreSQL or SQLite; frontend sessions use JavaScript.
- Trade feedback. You and your partner rate each other on rubrics after the session; paid members also get an AI transcript and grade.
An interviewing.io session
- Choose the subject, and an interviewer from a specific company if you want one.
- Meet anonymously. Your interviewer has none of your details, and the interviewing.io homepage describes the session as audio and chat with no video.
- Solve the problem out loud. The FAQ says questions are similar to real backend or full-stack interviews at top companies.
- Get an in-depth rundown of what you did well and how to improve.
- Unmask and connect with your interviewer afterward, or stay anonymous.
The vetting is the point of paying. Per its FAQ, every interviewer has worked at a FAANG or FAANG-adjacent company, has at least 4 years of experience and at least 20 interviews conducted for that company, and passed screening plus 2 trial interviews.
Who each one fits
Pramp (Aced Practice) fits you if you need volume, you're on a budget, you want practice on camera, or you want to sit in the interviewer's chair, which teaches you quickly what a clear answer sounds like. It fits less well if you need expert judgment: your partner is another candidate, so the feedback is only as good as the person you're matched with. It also needs a desktop.
interviewing.io fits you if you're an experienced engineer with a big-tech loop coming up, you're preparing for system design, staff-level or manager rounds where peer feedback is weakest, or you freeze in front of strangers and want the stakes lowered by anonymity. It fits less well if you need daily practice, if you want feedback on how you come across on camera, or if you're not interviewing for an engineering role.
A sensible order: two or three weeks of free peer mocks, one paid interviewing.io session about two weeks before your onsite, then more peer mocks focused on whatever that session exposed. Our system design mock interview script helps you run a useful peer session on design rounds.
A third option: CoPilot Interview for solo reps
Peer sessions need a partner and a time slot, and expert sessions cost money each time. For practice on your own schedule, CoPilot Interview is a desktop app for Windows 10+ and macOS 12+ whose Mock Interview mode builds an interview from your résumé and a job description. You choose the level, 3, 5 or 8 questions, the mix of behavioral, technical, system design and coding questions, and your coding language. It reads each question aloud, scores your spoken answer out of 10 with what to fix and a model answer, and ends with a report card. The browser AI mock interview offers 113 real questions across 9 tracks with nothing to install.
| Tool | Who asks the questions | Free option | Paid from | Best for |
|---|---|---|---|---|
| CoPilot Interview | An AI interviewer, from your résumé and the job description | 15 minutes every day, all four modes, no card or signup | $14.99/mo Standard (sale; regular $19.99); hour packs from $5.99 | Best choice for solo spoken reps on your own schedule, built from your résumé and the job description and scored out of 10 |
| Pramp (Aced Practice) | Another candidate | 5 peer mocks a month | Aced Pro $79/mo | Free practice with a real person |
| interviewing.io | A senior engineer | AI Interviewer | From $179 per session | Expert feedback before an onsite |
