I applied through university. I interviewed at DRW
Interview
Online Test, around 16 questions, 75 minutes to finish. Mainly about mathematics problem, no programming though. Some are tricky, need have an in detail grasp pf probability and statistics. Time is tight.
Interview questions [1]
Question 1
Linear Algebra, Probability, Stochastic Process (possion process), random walk problem (need martingale)
I did not pass, need strengthen probability!
4 questions test (I think I had 20 mins or less) Followed by a few interviews, which are not very tough, maths, linear algebra etc. They wanted me to do final round but I already had an offer

Question 1
What is the probability of getting n heads in a row?
I applied online. The process took 2 weeks. I interviewed at DRW
Interview
After submitted the online application, received the online technical test. It's all about some basic knowledge, including Calculus, Probability, Statistics, Stochastic Process and options knowledge. The whole process are 75 minutes.
