Trexquant Investment Alpha Researcher interview questions

1) Resume Shortlisting 2) Hangman assignment 3) HR round with one medium level leetcode question. The problem with this round is that it is taken by HR then why did she ask technical question when does not have any idea? She will share a link for leetcode and sit like a statue, she is not going to help you and neither she is interested in your intuition. She just focuses on whether all test cases are passed or not. Interview is interactive process, interviewer helps candidates if they are doing some minor mistakes but she does not have any idea about coding and still taking technical interview. I could not solve that question under 20-25 minutes but the problem when they have shared assigned and when you invested your time in assignment then what is the purpose of this leetcode question? If they want leetcode first take leetcode round then assignment. I invested a lot of time and still I was not asked a single question about assignment. 4) I did not get into this round but I think it was the last round with CEO where he asked about hangman assignment and alpha.
