Free peer-to-peer mock interviews with real people — genuinely good, and free. The catch is scheduling and the quality lottery.
Pramp, now running as Exponent Practice, pairs you with another job seeker and you interview each other. It covers data structures and algorithms, system design, product management, behavioural, frontend and data science.
Live peer-to-peer video sessions. You are matched with another candidate and take turns interviewing each other for 30–45 minutes.
Free. Their site states it aims to provide tech interview practice for free. Exponent's wider course library is a separate paid subscription.
“Tell us when and what you want to practice and we'll pair you with an optimal peer.”

Answered honestly, because a comparison page where the author wins every row is an advert and reads like one.
| Exponent Practice (formerly Pramp) | MockLive | |
|---|---|---|
| Availability | You book a slot and need a peer to show up. Time zones and no-shows are part of the experience. | Starts the moment you click, at 3am if that is when you are free. |
| Who interviews you | Another job seeker, whose skill and preparation vary session to session. | The same interviewer every time, which is worse for surprise and better for measuring whether you improved. |
| Feedback | Whatever your peer chooses to tell you, in their words. | A scored report against a fixed rubric, with the transcript and every answer replayable. |
| Scope | Tech interview formats. | Any role, 47 languages, plus IELTS Speaking. |
You are preparing for a technical interview, you can commit to scheduled sessions, and you want a human being on the other side. It is free — there is no good reason not to use it as well.
You want to practise at 2am the night before, you want the same measurement each time so you can see movement, or you are preparing for something outside the tech-interview formats peers cover.
Everything above about Exponent Practice (formerly Pramp) was read from their own site on 12 August 2026. Pricing and features in this category change without announcement — if what you see there differs from what you read here, theirs is right and ours is stale. We would rather you tell us than assume we meant it.
The biggest name in AI interview tools, and mostly a different product: its headline feature runs during your real interview, not before it.
Anonymous mock interviews with engineers who actually work at FAANG. The strongest option in this list for senior technical interviews, and priced accordingly.
The first session is free and needs no card. It ends with a scored report against a fixed rubric and every answer replayable — which tells you more about whether this suits you than any page like this one can.
