Phone Screens

After the OA, expect $2$-$4$ phone screens. The first is often HR asking about motivation: "Why quant?" "Why this firm?" Technical screens last $30$-$60$ minutes and cover probability, expected value, and betting scenarios.

Jane Street has $4$ phone rounds that get progressively harder. Citadel mixes behavioral and technical in a $45$-$60$ minute video call. Think out loud. Your process matters as much as your answer.
