I applied online. The process took 2 months. I interviewed at Two Sigma in Jan 2021
Interview
One day with 3 hours of technical interviews and if you do well you move onto the next day which is 3 hours of behavioral interview. The technical interview process consisted of 3 technical interview questions which each took one hour. They were each conducted by different engineers. The behavioral interviews were also split and conducted by two engineers and an engineering manager.
timed coding oa, followed up with phone interview, then final round interviews in-office. the recruiter was very flexible with deadlines, and allowed the oa deadline to be extended. topics were not out-of-the-ordinary for freshman computer science majors
Interview questions [1]
Question 1
debugging, fairly straightforward if you know data structures.
The first round was alright and had two questions which were like a medium difficulty.
Then the second round was a bit more complex, because the question was to debug a code about Tree Maps
First there's an online assessment, then a technical interview, then a two part final interview that is technical and behavorial. Although, it is possible to get cut after the final round technical interview and not make it to the behavorial. It was my first interview ever and I basically flunked every technical question (got 2/3 in the OA, first tech interview went awful as I had no clue what I was doing, final round was even worse). Although, somehow made it to the final.
