Prop Trading Interview Questions for Quant Developers
The same round is marked differently depending on the seat you are interviewing for. This is the prop trading set as it applies to quant developers.
35 questions, all free to practise. The split is 10 easy, 23 medium, 2 hard. The topics that come up most are programming & dsa (12), calculus (10), combinatorics (8), brainteasers (3).
