They came to our campus and did an info session, candidates that were interested in the position were asked to take a 8-minute 80 questions math test (only + - x /, very hard to complete 100%). Right after the info session I was told that I got selected for a formal interview on the next day. On the second day, I did interview with HR, very easy, asked about why I wanted to be a trader, why do I want to join this particular company. Things got tough with the technical interview, it was all math brain-teasers questions (what day would it be in 10 or 1000 years). They expect you to solve it in a quick and accurate manner.

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)
