The process took 2 weeks. I interviewed at Optiver (Chicago, IL) in Dec 2022
Interview
First round is assessment round which includes 5 Zyvo tests :
Test 1. 80 questions in 8 minutes
Test 2. Neuro-assessment games - 1 hr
Test 3. Sequences questions - 25 minutes 26 questions
Test 4. Probability questions- 15 minutes 10 questions
Test 5. Personality test
Every test is pass or eliminate. So, give your best. Personality test isn’t considered in final score. I passed all 4 tests. Still was rejected for further interview rounds. I don’t what are the hiring needs currently ( I guess it can be because of the fact that I’m a international candidate and they might not be sponsoring for internships ). Best of luck to all.
Interview questions [1]
Question 1
15*5/3 = ?
1 2 7 5 13 9 ? - next in series
Probability questions difficulty increased as you move forward with questions. It’s either you know how to solve question by your earlier experience or you may not be able to solve it in 90 seconds time limit per question,
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.
