Candidatei-me online. Fiz uma entrevista na empresa Optiver.
Entrevista
8 min mental arithmic, pass mark 55 out of 80 questions (negative marking), 30min number sequence series pass mark 21 out 26 (no negative marking), 10 min harder mental arithmic, pass mark 23 out of 40 questions( negative marking). not very difficult , all you need is just do some practice
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.
