Quick Answer
Mock interview platforms fall into four types: peer platforms (Exponent Practice, free with limits), expert marketplaces (interviewing.io, IGotAnOffer, PrepFully), AI interviewers (Huru, Interviews by AI, Final Round AI) and English coaching for tech interviews (Mockly). Most assume fluent English. If English is part of your gap, combine a cheap source of volume with a coach who corrects your English in context.
⚡ Quick Stats
The Four Types of Mock Interview Platform
- Peer platforms. You interview another candidate and they interview you. Cheap or free, great for volume; quality depends on your partner.
- Expert marketplaces. You pay an engineer or manager, often from a target company, for a realistic mock and a verdict. Expensive; strongest company insight.
- AI interviewers. Software asks questions and scores your answers. Unlimited and cheap; cannot judge technical depth like an engineer.
- English coaching for interviews. A coach runs the round and corrects how you say it. Built for non-native speakers; fewer slots than a marketplace.

Try the Mini AppWhat Non-Native Speakers Need From a Mock
A typical mock gives you a verdict: hire or no hire, and a few notes. For a non-native speaker, the verdict often hides the real cause. “Communication could be clearer” does not tell you which sentence went wrong.
- Line-level corrections. The exact phrase that sounded unsure, and what to say instead.
- Mistakes that change meaning, not every mistake. “Actual” for “current” matters; a missing article usually doesn't. See 20 English mistakes in tech interviews.
- A second attempt. Saying the answer again, correctly, in the same session. That is where it sticks.
- Technical judgement. Someone who can tell whether your design or SQL answer works, not only whether it sounds fluent.
How to Combine Them
- For volume: an AI tool (Huru is free) for behavioural reps most days, and peer mocks on Exponent Practice for coding.
- For English: Mockly's free 30-minute trial to find your main habits, then a session per round type you expect.
- For company insight: one expert mock on IGotAnOffer, PrepFully or interviewing.io in the final week, once your English is not the bottleneck.
