The first interview was three brain teasers, known basic probability and be able to explain the reasoning behind your answer and talk the interviewer through your approach. The second interview started with some basic fit questions (Why Jane St? Why Trading? Why should we hire you?) then another brain teaser.

Many rounds of brainteasers, some of which are more rapid fire in nature and others which require you to flesh out a detailed answer to a complex problem. Be well rested and well prepared!
