DS interview practice,
without the paywall.
754 questions across 8 modules — the way top companies actually test: SQL, Python, statistics, experimentation, product metrics, ML, behavioral, and system design. Two progressive hints before every solution, plus the interviewer's note on what each question is really evaluating.
Why give away 754 questions?
Because our team comes from data science, and this is us giving back to the community we come from. The big platforms charge ₹1,500+ a month to rent you questions. We wrote every question, hint, and interviewer note ourselves — and we'd rather they help people than sit behind another paywall. Consider it proof of how we build.
Made for data scientists. Not just for data scientists.
This practice tool is our gift to the DS community we come from. But PrepMyRez itself was built for every job seeker — a career acceleration platform that covers the major steps of the journey: finding your direction, building your resume, practicing interviews, tracking applications, following up. Whatever you're chasing, there's something here for you.
This is free because we mean it.
Keeping all of this open is our proof that we're on the job-seeker's side — not the other way around. But building, updating, and maintaining tools costs real money: servers, AI, time. When you buy a plan, you unlock the AI tools for yourself — and help us build more free tools like this one and keep PrepMyRez running for the job-seekers who come after you. That's the deal.
SQL and Python are open to everyone. The other six need a free account — 30 seconds, no card, still completely free. Your progress always stays on your device.
