The PEAK6 interview funnel
1. Online Assessment
~1 hr timed test after you apply; HackerRank coding for software roles (reported)PEAK6 follows every application with an assessment. Trading candidates report a timed test of arithmetic, probability, basic finance, number series and logic puzzles, about a minute per question; one report adds personality questions. Software roles: about two HackerRank problems in around 90 minutes (interval/scheduling-style). Drill: mental math, number sequences, probability. No PEAK6-tagged problems yet; the list fills as reports arrive.
2. First Interview - Technical + Behavioral
1 hr - Zoom, with a trader (per PEAK6)PEAK6 lists a one-hour Zoom interview with a trader. Candidates describe a behavioral half (why trading, why PEAK6, what is happening in markets) and a technical half: mental math, probability, expected value, brainteasers, estimation such as sizing a market or setting odds. One report: about 30 mental math problems in four minutes. Practise: mental math, Fermi estimation, expected value.
3. Final Round - Trading Case + Market Making
Half day - Zoom (per PEAK6); older reports describe an in-person Chicago superdayPEAK6's final: half-day Zoom with leadership and future teammates; software finalists report live coding (parsing a CSV or quote feed).
Candidates report back-to-back trader and manager interviews (probability, brainteasers, mental math), a trading case study and market making. In one account you quote the sum of six dice rolled one at a time, updating as they land and tracking position and P&L (reported); others play as a group. Rehearse: Make a Market, card market table, market-making guide, options Greeks guide.
4. Leadership + Fit Conversations
Part of the final; decision in about two weeks (per PEAK6)Several reviewers say PEAK6 weights team fit heavily, with more than one behavioral conversation and time with leadership during the final. PEAK6 says it may take up to two weeks to share a decision. Prepare with behavioral questions for trading firms and questions to ask your interviewers.
