I applied online. The process took 4 weeks. I interviewed at Two Sigma (New York, NY) in Sep 2019
Interview
Hackerrank, phone screen (with coding questions), then onsite. My interviewer seemed disintrested and made it very clear he didn't want to be there and that he had better things to do.

Question 1
Create your own random number generator given specific requirements
2 out of the 3 interviewers were very helpful. They genuinely want you to pass. It is just LeetCode. Practise the Medium ones and a little bit of System Designs.
Received the OA in January and received first round technical invite after a few weeks, LC medium/easy for the OA online 60 minute hacker rank. Then 3 60 minute technical interviews.
