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.
I applied online. I interviewed at Hudson River Trading (Chicago, IL) in Oct 2022
Interview
Phone interview composes questions about computer organization and algorithm. No coding is needed. But you need to describe the algorithm. Still in progress of the interview. Move on to the coding interview
