What the Coding tests

State complexity and optimize.

QuantVault maps 7 practice problems to this round. By topic, the biggest groups are coding (6), market microstructure (1); by difficulty, 0 easy, 2 medium and 5 hard. 5 of them were reported by candidates who interviewed at DRW, most recently in Jul 2026.

Who takes this round: Software Engineer candidates. See the full DRW process and who takes each round.

How to prepare for the Coding

  • State complexity first, then optimize.
  • Data-structure design -- streaming medians, matching engines.
  • Know your language internals (C++ if applicable).
