The first step is to take the written tests. I did it remotely and use the webcam and have to send back the written answers. Then, some technical phone interviews follows.
I applied online. The process took 1 day. I interviewed at Quantlab in Nov 2022
Interview
this is just a phone call, lasts for 30 min, very friendly, went over the following steps. This is the first step I guess,it hasn't got to anything techinical yet.
Applied for a quant researcher position, and they kept interviewing for a c++ developer position. The first round was a mathematics exam, followed by a coding challenge. Had 2 more rounds of interview after that.
Online zoom tests. Everybody was on zoom with video on and solving the same set of problems. A bit stressful but in general okay. Problems were not hard to solve, but they were very broad.
Interview questions [1]
Question 1
10 high school/college math + physics problems, not hard to solve, but you do need to prepare.
