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
Acudí a una entrevista en Two Sigma (New York, NY)
Entrevista
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

debugging, fairly straightforward if you know data structures.
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.
