Practice for your Five Rings interview

A HackerRank test of 17 questions with one minute each, then fast probability interviews: prepare with real interview questions and the dedicated course.

The Five Rings interview process

Five Rings screens your CV first, then sends a HackerRank online assessment of 17 questions, each with its own fixed minute: mostly mental maths and estimation, with some probability and no coding or finance. If you pass, a fast first interview follows, with a long series of short probability and statistics questions, then a behavioural interview of about 15 minutes with HR. The remaining interviews are video calls with traders, each built around one problem, often a game or a betting scenario, that gets harder with every follow-up. Every interview takes place by phone or video.
