A question bank is the start, not the finish. Reading hundreds of questions feels productive, but what changes an interview is answering a few out loud and fixing them. So our pick for 2027 is CoPilot Interview, which we make: a browser demo with 145 real questions across 10 tracks that grades your answer, and a mock interview that builds questions from your résumé and the job. If you want volume, several apps offer more questions than we do, and for coding, LeetCode is hard to beat. Here is how they compare, and how to use any bank well. Live-help tools are in our full comparison for 2027.

How to use any question bank
- Pick twenty questions likely for this job, not two hundred.
- Sort them into six groups, each answered by one of your stories.
- Prepare one story per group with a result in it.
- Say each story aloud three times over several days.
- Then ask a tool or a friend to surprise you with a question from the list.
- After every real interview, add the questions you did not expect.
Why fewer questions work better
Most interview questions are versions of about six: tell me about yourself, why this job, a conflict, a failure, a success, and something you did under pressure. Candidates who prepare six good stories can answer most of what comes up, whereas candidates who memorize two hundred answers sound rehearsed and get lost when a question is worded differently. A large bank helps you find the patterns, and our comparison of prep apps shows which apps organize them well. If you only want one thing to try, open the demo, pick your track and answer one.
When volume does matter
- Coding rounds, where pattern recognition comes from many problems.
- Technical certifications and licensed fields, where facts need to be recalled exactly.
- Very specific knowledge rounds, such as accounting standards or clinical protocols.
- Languages other than your first, where hearing many phrasings helps.
- Even then, some of the practice should be spoken and timed.

Frequently asked questions
What is the best interview question app?
Our pick is CoPilot Interview, which we make, because it checks your answer rather than only listing questions. Interview Pilot and Interview Sidekick advertise more than 10,000 questions, and LeetCode leads for coding.
How many questions should I practice?
About twenty likely ones for the job, grouped under six stories. Volume matters mainly for coding and knowledge rounds.
Is there a free question bank?
Yes. Our demo at /try has 145 with no signup, and this site has role-by-role lists. General AI assistants can generate questions from a job posting.
Should I memorize answers?
No. Prepare stories and say them aloud several times. Memorized answers fall apart when a question is worded differently.
What about coding questions?
LeetCode is the usual choice, and it has free problems. Practice explaining your thinking out loud as well.
Rehearse the answer out loud
The browser demo runs 145 real interview questions across 10 tracks and shows a structured answer to compare with yours. Free, no signup.
