Trexquant Investment interview questions

1 phone screen, 1 round with general problem on market to portfolio, 2 rounds ( 1 online and 1 onsite ) of Leetcode medium and a resume discussion and general fit with panel . Expect a hangman challenge which I did not get but it can happen .

First round is HR reach out discussing resume and sponsorship. Second round is 45 min with resume questions, green book stuff (probability and math), then leetcode stype questions, not too hard overall. Third round is superday where you present a project you work on which I suspect is where a lot of there alpha ideas come from since people present projects from their previous internship or job. Final round is talking to the CEO. Finished the CEO round answering a bunch of technical questions right as well as a leetcode problem, but unfortunately didn't get an offer. CEO does not seem very smart and struggle to understand very basic things when discussing my answer on technical questions he prepared. Honestly I think whether you get an offer or not in CEO round depends on his mood on that day.
