I applied online. The process took 3 weeks. I interviewed at Two Sigma (New York, NY) in Mar 2018
Interview
hr screening, coding test , phone interview, and schedule another round of phone interview and then suddenly cancel it. do not think it is a good process to find correct candidate for them.
Interview questions [1]
Question 1
the same two coding problem every year, basic prob problem and finance problem which i do not think has specific answer, and do not feel that the interviewer is professional in asking the question clearly so as to limit the answer within certain range of topics.
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.
