I applied online. The process took 1+ week. I interviewed at Hudson River Trading (New York, NY) in Mar 2021
Interview
Process is long. Online coding assessment on codility, preliminary phone screen, then another phone screen, then on-site. Interviewer tried to get you to talk about different topics without explicitly asking about it, which I thought was weird.
I applied through a recruiter. I interviewed at Hudson River Trading (New York, NY) in Apr 2026
Interview
First round was a unproctored codesignal with three questions. Then a live Coderpad for one question. Then a one hour technical with coding and system design. Then an onsite interview
The test was 3 questions on Code Signal, with the difficulty level of Leetcode medium to hard. The questions were about string manipulation/ graphs/ backtracking algorithms. Time limit of 2 hours, very tight on time.
