I applied through a recruiter. I interviewed at Hudson River Trading in Jan 2021
Interview
Contacted by a headhunter, applied online and was sent a coding challenge that consisted of 3 questions and was given 3 hours to complete it. Questions were easy-medium level, mostly testing data structures and coding knowledge. Scored 88% but eventually heard back that hiring is frozen for this position
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. The process took 1 week. I interviewed at Hudson River Trading in Oct 2022
Interview
received online assessment on codesignal first; followed by a phone interview with an algo engineer at HRT, overall experience is okay, the interviewer is quite nice. Got rejection 3 days after the phone interview.
