I applied through college or university. The process took 4 weeks. I interviewed at Optiver (Chicago, IL) in Nov 2010
Interview
Talked to HR representative at job fair and was invited to sit-down for a numerical math test the next day. The exam consisted of 80 MC questions testing simple arithmetic ability. The cutoff score was ~52. I was called a few weeks later and had a behavioral interview over the phone with HR rep, and later was invited to the Chicago office for final round interviews. The final day of interviews consisted of 3 - 30 min interviews and 2 more math tests (1. harder arithmetic test, 2. sequences). The first two interviews were both behavioral/fit interviews and the final one involved some financial/options questions.
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.
