I applied through college or university. I interviewed at Optiver
Interview
Dropped resume on campus recruiting event, then received invitation for numerical test in 4 weeks. Numerical test was not difficult, but need to be fast, and be careful because you will be penalized on wrong answers. After the numerical test, was asked to move on for behavioral interview. Did not get offer.
Interview questions [1]
Question 1
Numerical test was basically mental calculations, 80 problems in 8 minutes.
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.
