Quant Interview Study Group Guide
How to run an effective quant interview study group with prompt rotation, mock roles, feedback, and accountability.
Candidates preparing for quant interviews with peers.
Keep the group small
A useful group is usually small enough that everyone solves and gives feedback. Large groups often turn into passive watching. Two to four committed people is enough for mocks, prompt rotation, and accountability.
Rotate roles
Use three roles: candidate, interviewer, and observer. The interviewer asks follow-ups. The observer tracks assumptions, method choice, communication, and recovery. Rotate so everyone practices both solving and evaluating.
Pick prompts by goal
Choose prompts that match the current weakness: probability setup, expected value, market making, coding, or communication. Random hard prompts are less useful than targeted prompts with careful feedback.
Concrete group session
A 90-minute session can run two 25-minute mocks, two 10-minute reviews, and a final 20-minute repair-plan discussion. End with each person naming one drill before the next meeting.
Give feedback that changes practice
Feedback should be specific and actionable. "Be clearer" is weak. "State whether draws are with replacement before calculating" creates a repair target.
Common mistakes
Study groups often become social problem browsing. Keep sessions timed, roles clear, and review tied to next actions. Otherwise solo focused practice may be more useful.
Practice the pattern
Use the LeetQuidity curriculum and calibration to turn this topic into a focused practice plan.
