J'ai postulé en ligne. Le processus a pris 1 jour. J'ai passé un entretien chez Optiver (Londres, Angleterre)
Entretien
8 minute maths test, followed by 2 further tests - maths and logical reasoning if you pass the first test. Only if you pass test 1 can you do test 2, only if you pass test 2 can you do test 3. 25 people turned up and 22 of us were kicked out having only done 8 minutes of maths. A complete joke, waste of time and money (no transportation costs reimbursed).
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.
