What D.E. Shaw asks in the DSA round

D.E. Shaw combines hard DSA with probability, puzzles and aptitude. Expect strong maths screening before the coding rounds.

Across the 178 questions on this page, the weight sits on these patterns:

How to prepare for the D.E. Shaw interview

  1. 1. Start at the top of the list above. The patterns are ordered by how often D.E. Shaw uses them, so the first two or three buy you the most coverage per hour.
  2. 2. Solve by pattern, not at random. Doing eight dynamic programming problems in a row is what makes the ninth recognisable in an interview — jumping between topics does not.
  3. 3. Tick problems off as you go so the gaps are visible. The per-pattern counts tell you which D.E. Shaw topic you have actually covered.
  4. 4. Write the approach before the code. D.E. Shaw interviews are judged on the reasoning as much as the working solution.
  5. 5. Pair this with the pattern guides when a topic is new, and the system design sheet if the role is senior enough to have that round.
  6. 6. If this is a campus or off-campus drive rather than a lateral move, the placement preparation guide covers the stages around the DSA round — aptitude, core subjects and the HR interview — in the order they actually happen.

Which topics should I focus on for a D.E. Shaw interview?

Dynamic Programming, Modified Binary Search, Bitwise XOR come first — the patterns on this page are ordered by how often D.E. Shaw leans on them, so working top-down spends your time where the interview actually is. The full order is Dynamic Programming, Modified Binary Search, Bitwise XOR, Greedy, Prefix Sum.

How long does it take to finish the D.E. Shaw sheet?

At roughly 25 minutes per problem — reading it, solving it and writing the approach down — 178 problems is about 74 hours, or 7 weeks at ten hours a week. Most people do not need all of it: the first two or three patterns cover the majority of what gets asked.

Is this D.E. Shaw question sheet free?

Yes. Every problem, the pattern grouping and the progress tracking are free and need no account. Progress saves in your browser, and signing in with Google only adds syncing across devices.

Can I track which D.E. Shaw questions I have solved?

Yes — tick a problem on this page and it stays ticked. The counts per pattern update as you go, so you can see which of D.E. Shaw's topics you have actually covered rather than guessing.
