Thanks for your question! Our interview process varies by role, but generally includes a take-home coding test, one or two technical phone screens, and an onsite with 3–5 rounds. For algo developer roles, you can expect math-heavy topics like statistics and probability in addition to C++ or Python programming. Python and C++ Software Engineer interviews do not assess quantitative skills. Those roles focus more on topics like programming, debugging, and systems knowledge.

Beyond technical skills, we’re looking for strong problem-solving, communication, and a collaborative mindset. If you'd like to dig more into our software engineering interview process, we published a blog a few years ago focused on campus interviewing, but they're similar processes: https://www.hudsonrivertrading.com/hrtbeat/interview-at-hrt/

Design Engineer here, curious if HRT has design roles open. Noticed that Two Sigma and Jane Street are expanding their teams, is HRT working on the same?

CS Phd student here: took an online assesment recently (for internship role). 3 questions in total. None of them were puzzle-type question, or required advanced data structure or algorithm knowledge, but they were more of implementation focused. One of the questions took me about 80 lines, in Python, which is quite a lot for these sort of tests.

I think they were the kind of problems where if you didn't break them down into smaller chunks, individually test each of them- it'd be quite hard to get them working in such a short time.
