I applied online. The process took 3 months. I interviewed at Two Sigma (New York, NY) in Dec 2019
Interview
1-2 phone screens, followed by a half to full day (depending on if you passed the first half) onsite interview with several rounds of technical and design questions. It was well organized and good experience, even though many got sent home halfway through the onsite
Interview questions [1]
Question 1
Mathematical/probability technical question, discussion and whiteboarding
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.
