What Robinhood asks in the DSA round

Robinhood pairs medium-hard DSA with a trading-flavoured design round on order matching, market data and correctness under concurrency.

Across the 15 questions on this page, the weight sits on these patterns:

How to prepare for the Robinhood interview

  1. 1. Start at the top of the list above. The patterns are ordered by how often Robinhood 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 breadth-first search 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 Robinhood topic you have actually covered.
  4. 4. Write the approach before the code. Robinhood 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.

At roughly 25 minutes per problem — reading it, solving it and writing the approach down — 15 problems is about 6 hours, or 1 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.
