I applied through college or university. The process took 3 weeks. I interviewed at Optiver (Amsterdam) in Jun 2015
Interview
Dropped Motivation letter and CV. Invited for arithmetic tests. 3 rounds. 1st round is toughest, make sure you prepare well and don't make too many mistakes. Overall, tests are quite doable.
HR Interview is nice, nice people, just make sure for yourself you want this job and you will do well.
Technical interview is challenging. They push you to the limit. Stay calm and stay sharp
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.
OA was weird and hard. there was only three sections (i think) this year compared to 5 last year. questions are weird and I don't know how they can judge your ability base on that.
