I applied online. I interviewed at Two Sigma in Oct 2021
Interview
Was given an online coding test. I think they want 100% on all the hidden tests.
They also require you to upload transcripts from all degrees, which is very weird.
The recruiters were accommodating when I asked if I could take the test later due to clashes with my research deadlines.
Interview questions [1]
Question 1
Was given two coding questions. They were easy-medium. I got 100$ one one and 24/27 test cases passed on the other. By the time I realized my mistake (a stupid one line error in my list comprehension), the time was up and I could not fix it.
Was given the rejection after a few days, so I think they want 100% accuracy on all the hidden tests, doesnt matter if your logic is correct or not (my code was heavily commented on).
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
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.
