Two Sigma interview questions

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.

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
