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 2 weeks. I interviewed at Two Sigma in Oct 2017
Interview
The interview wasn't very professional. I was contacted with a HR and given an coding exam. After passing the coding exam there was a phone interview. The guy was 10 minutes late and didn't apology for it. HR said there should a one-hour long interview of both technical and non-technical questions. So I prepared it hard for a week. It turned out we just spoke for 20 minutes and they didn't give me any technical question. The guy wasn't very patient and want it end asap. I got a rejection on the same day. Maybe they don't have head count for it or simply not interested in hiring more quants.
This is a total waste of my time.
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.
