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)

Average interview
Application
I applied online. The process took 2 weeks. I interviewed at Optiver (Sydney) in Mar 2017
Interview
Applied online and was asked to attend the math test on the following day. The first one is 80 arithmetic calculations within 8mins. I just finished it, can't guarantee the accuracy though. The second test is filling the series. You need to finish 26 questions within 30mins. I only figured out 23 questions. Received an email one hour later, saying that I passed the tests. I got a phone interview on the following week. It was quite general, but very detailed. It lasted 30mins. I got a call today from Optiver, inviting me to the 1st round interview.
Interview questions [1]
Question 1
What subject you didn't enjoy for your bachelor degree?
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.
