I interviewed on zoom with three different interviewers. The first was talking to a recruiter about interview processes and why I am applying and going over my resume. The second was with a quant researcher about my resume, past research and domain knowledge and technical questions. The third round was with another quant researcher about past research and some more technical questions. I didn't proceed after that.

Question 1
statistics and regression questions and some math brainteasers
I applied online. The process took 4 weeks. I interviewed at Two Sigma (New York, NY) in Nov 2017
Interview
Medium-difficulty HackerRank coding test (2 problems over 3 hours), then a phone screen with a quant in which I was asked about my research as well as some open-ended questions about problems Two Sigma faces (how would you predict Y if you had data of the kind X). Then on-site, where I had five interviews with Two Sigma employees, which focused on my research, probability brain teasers, general brain teasers, white-board coding, open-ended applied questions.

Question 1
Q: If Two Sigma had access to all of LinkedIn's data from the past decade, how could it use that to predict stock prices?
The interview process typically starts with conversations with team members, followed by three rounds of technical interviews focused on data analysis, coding, and statistics. Each round includes follow-up questions that probe deeper into the candidate’s reasoning, methodology, and ability to apply concepts under realistic problem-solving scenarios.

Question 1
one question about citi bike problem, one about correlation
Interview mostly consisted of conceptual ML questions and general experience, with no coding. The interviewer was super nice, but they were looking for more experienced candidates, which my years of experience didn’t quite qualify me for.
