How to use this set

A path that works

1. 1

   Warm up on the 39 easy questions

   These are the ones Citadel Securities uses early in the screen to filter for clean reasoning. Time yourself, then move on once your answers feel automatic.

2. 2

   Drill the 118 medium questions

   Medium-difficulty questions cluster in the actual on-site rounds. Run them on a stopwatch and revisit any you missed two days later.

3. 3

   Pressure-test on the 109 hard questions

   Hard questions simulate the final round. Skip looking at solutions for at least 20 minutes, then write up your approach as if you were explaining it to the interviewer.
