Step one is an online code challenge via HackerRank. Step two is a phone interview with a member from the engineering team. Step three is an in-person interview on school campus. Step four is an onsite interview day.
I applied online. I interviewed at Two Sigma (New York, NY) in Jan 2021
Interview
The interview demands a coding contest on HackerRank. You will be given three questions. The first two questions are easy (using classes) and the last one is harder. Usually demand your programming knowledge.
