J'ai postulé en ligne. Le processus a pris 3 semaines. J'ai passé un entretien chez Optiver (Chicago, IL) en oct. 2016
Entretien
This company is terrible. They asked me to finish the mental maths part and then scheduled a phone interview with me. During the phone interview, they spent 5min to explain they don't sponsor people and hang up the phone call directly. I don't understand if you don't sponsor people, why are you wasting my time (I have specifically indicated that I'm an international student and need sponsorship in the online application). If you are also an international student, don't bother to apply for this company.
The whole process is so unorganized and unprofessional. I don't understand who want to work for them. On the other hand, Chicago wouldn't be my first choice after all.
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.
