Standard - tough maths questions on probabilities and different risk games. Nice smart people who challenge you throughout the process. Tough overall experience but good relatability to role and requirements.

spent about 1.5 months pretty much purely dedicated to preparing for interviews for all the pre-penultimate programs (Optiver, IMC, JS, SIG, Citadel, etc). I used these resources: Green book (Really good starter but I got bored of it after a few weeks) EverythingQuant (Went through literally every single interview prep question, went through the interview guides, and completed the probability course just to make sure I covered all bases) Briefly read through this guide Watched coding Jesus in my spare time (not sure if this helped directly lmao but he’s a great creator and very informative)

Mental math test, beat the odds, online puzzle like games etc online, brain teasers during physical interview and a behavioral interview where they want to assess how competitive and assertive you are.
