Hudson River Trading

Hudson River Trading (HRT) is renowned for its rigorous and structured interview process, emphasizing technical proficiency, problem-solving abilities, and effective communication skills. Candidates can expect a multi-stage evaluation, including a take-home test, phone interviews, and an onsite interview day. The take-home test typically involves timed coding challenges, often hosted on platforms like HackerRank or Codility, where candidates are encouraged to utilize available resources and focus on testing their code thoroughly. Phone interviews usually consist of technical discussions and programming exercises, assessing knowledge in systems, data structures, and problem-solving. The onsite interviews delve deeper, evaluating programming skills, systems-level knowledge, and problem-solving approaches, while also assessing collaboration, teachability, and communication.

For a problem like "Matrix Rotation," HRT would assess candidates on their understanding of algorithms and data structures, particularly those involving two-dimensional arrays and matrix manipulations. Proficiency in languages such as C++ or Python is essential, as these are commonly used in HRT's technical environment. Candidates should be prepared to discuss their thought process, demonstrate clarity in their approach, and effectively communicate their solutions. HRT values candidates who can break down complex problems, work collaboratively, and adapt to different problem-solving strategies. It's also beneficial to practice coding problems that involve matrix operations and rotations to build familiarity with such tasks. (hudsonrivertrading.com)
