What is the difference between interview prep and mock interview tools?

A mock interview tool runs practice interviews. Interview prep is wider: it also covers courses, question banks, a prep sheet for a specific job, and in some products live help during the real interview. Several tools on this page do more than one of these.

Which tools help with technical interviews?

Aced, formerly Exponent, lists courses for software engineering, system design, product management, data science and machine learning, plus peer mock interviews and practice with coaches. The other tools here are aimed at interviews in general.

Can I prepare for one specific job posting?

Yes. Interviews by AI writes practice questions from a job description you paste. Crush Job's Interview Killer builds a battle card that matches the posting's requirements to lines from your resume, with STAR stories and likely questions for each stage.

Is it OK to use AI during a real interview?

It depends on the employer. Using AI to prepare is broadly accepted. Using it for live help during the interview is contested, and some employers forbid it. Check the rules for your interview first. Crush Job describes Crush Coach for what it does and does not sell it on concealment.

Are any AI interview prep tools free?

Several let you start free. Aced offers a free account. Huru says it is free for everyone. Interviews by AI has a free Basic plan. Big Interview offers a free course. Crush Job's Free plan needs no card and includes 1 battle card every month and 1 scored mock every month.
