A free mock interview, with Prism.

Pick your role and answer 5 interview questions in your own words. Prism reads each answer and shows what you covered, what an interviewer also listens for, and one way to say it.

Hi, I’m Prism. Which role are you interviewing for?

5 questions, about 10 minutes. No score, just feedback.

How the practice works.

  • The bank’s questions

    477 interview questions for data science and AI roles, Easy to Hard, each with a model answer and its sources. A round mixes topics and levels, and skips the ones you’ve had.

  • Feedback, not a score

    Prism compares your answer with the bank’s: the points an interviewer listens for that you made, what worked and what to add. No marks and no verdict: it’s practice.

  • Your answers

    Kept like a chat with Prism: for 90 days, then deleted, and never used to train AI models. The AI assistant, in our privacy policy.

Every question and its answer is also in the interview question bank, with the companies where candidates reported it.
