Is the 1500 CP-31 sheet good for product company interviews?
Yes — 1500-ish problems are roughly LeetCode medium-to-hard, which is the level of harder product company rounds.

Curated by Priyansh Agarwal, ICPC World Finalist and AIR 1 in Google Kick Start, this sheet features all essential 1500-rated Codeforces questions. With a Master (India Rank 34) on Codeforces and 4000+ students taught, Priyansh’s expertise ensures that this sheet will help you sharpen your competitive programming skills and make steady progress
1500 on Codeforces is Specialist level. Specialists who solve Div. 2 C in most contests and want D within reach.
What these problems lean on: DP, Graphs (BFS/DFS), Constructive, Sorting with custom order, Modular arithmetic.
The usual wall at 1500: Graphs and trees appear as the core of the problem, not decoration, and constructive problems need a real argument for why the construction works.
How to practise it: Get BFS, DFS and a DSU template to the point where you write them without thinking, so contest time goes on the modelling rather than the code.

Yes — 1500-ish problems are roughly LeetCode medium-to-hard, which is the level of harder product company rounds.
BFS/DFS, basic DP, modular arithmetic and fast exponentiation. Everything else in the sheet builds on those.
There is no PDF here, and you do not need one. All 31 problems are listed in full on this page, free and without an account — and unlike a PDF the list remembers what you have ticked off, so you are not re-reading a static file to work out where you stopped. Use your browser's print view if you want it on paper.
Tick a problem on this page and it stays ticked. Progress saves in your browser straight away with no account, and the counts update per section so you can see which parts of 1500 Rated: CP-31 Sheet you have actually covered. Signing in with Google syncs it across devices.
At roughly 25 minutes a problem — reading it, solving it and writing the approach down — 31 problems is about 13 hours, or 1 weeks at ten hours a week. Treat that as a planning figure rather than a promise; the first pass through an unfamiliar topic is always slower.
Yes, completely, and no account is needed. There is no paid tier and nothing is held back — the sheet itself is by Priyansh Agarwal, and this is a free tracker for it.
Finish one. Sheets overlap heavily, so working several in parallel mostly means re-solving the same problems while never completing a full topic sweep. If you are not sure this is the right one for the time you have, the sheet comparison page puts the options side by side with hour estimates.
