How a PrepLinx mock interview works

  1. 1

    Choose the round

    Pick the role, the interview type and a difficulty (easy, medium or hard). Optionally add a job profile with your resume and the job description, so the questions relate to that job.

  2. 2

    Interview out loud

    The AI interviewer speaks, listens to your answers and asks follow-ups. It doesn't give hints or say whether you're right, just like the real thing.

  3. 3

    Get scored feedback

    A report with a 0–10 score for each dimension the round is graded on, strengths quoted from your own words, weaknesses, concrete improvements and an overall hiring signal, plus the full transcript.

Frequently asked questions

What is an AI mock interview?

A practice interview run by an AI interviewer instead of a person. On PrepLinx you speak your answers out loud, the interviewer asks follow-up questions the way a real one would, and you get a scored report at the end.

Is PrepLinx free?

You get 4 full interviews free, of any type, with scored feedback and no credit card. They don't expire.

How realistic is the AI interviewer?

It runs the round like a real interviewer: it presents the problem, answers brief clarifying questions, asks follow-ups, and doesn't give hints or tell you whether you're right. It also reads your code and whiteboard and asks about them.

What if I end a session early?

Sessions shorter than 3 minutes, or where you said very little, aren't scored, and the interview is given back to you.
