I applied online. The process took 1 week. I interviewed at Two Sigma (New York, NY) in Apr 2021
Interview
Typical brainteasers. I was sent a take home quiz with about 30 probability and brainteaser questions. Including: fibonacci series, bayes, geometric distribution, binomial probability. Did not have enough time to finish but questions were not too difficult
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.
Interview questions [1]
Question 1
statistics and regression questions and some math brainteasers
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.
