How Long Does It Take to Hear Back After a Hudson River Trading Interview?

Hudson River Trading does not publish wait times, and public candidate reports are scarce. HRT is a quantitative trading firm. Quantitative trading means trading with math models and automated software.

The waits in this answer are typical for companies of this size, not confirmed. Plan for about one to two weeks after the take home coding test. Plan for about one week between the two phone rounds.

Plan for one to two weeks after the full day onsite. End to end, four to six weeks is a sensible expectation.

HRT does publish what its stages are. That is the useful part. It tells you which silence is normal and which is long.

The round by round detail is in the HRT interview process.

Timeline by Stage

Does Hudson River Trading Send Rejection Emails?

HRT does not publish a rejection policy. A short recruiter email with no reasons is the normal outcome at firms of this type. HRT does not state whether every applicant gets a reply.

Written feedback per round is rare. HRT's own interview guidance says what interviewers watch: how you think, how you approach a problem, and how well you use a hint.

So the useful feedback happens during the round itself. Ask your interviewer direct questions in the session instead of waiting for a report later.

One HRT specific point belongs here. HRT writes that some candidates try to cheat the early stages with a large language model. A large language model is an AI system that writes code and text from a question.

HRT says the later stages are run in a way that makes cheating much harder. Your onsite work has to match your test result.

How to Follow Up

Send one email to the recruiter, not to an interviewer. Wait ten business days after the take home test. Wait seven business days after an interview round.

Hi [Name], thank you for the [round name] on [date]. I am still very interested in the [role] role at HRT. Could you tell me where my application stands and what the next step is? I am glad to wait if the team needs more time.

One follow up is enough. A second email adds nothing to your case.

Can You Reapply, and How Soon?

HRT does not publish a reapply policy. Six to twelve months is the common wait before a new application at firms like this. Use that time for a real change in your skills, such as a C++ project you can defend in detail.

HRT runs two talent communities on its careers site. One is for students in an undergraduate or graduate program. One is for people with full time work experience.

Joining keeps you in the recruiting system between applications.

What to Wear

HRT's own post says the process starts with Zoom calls, so most rounds are on video. Wear a plain shirt in one solid color. Test your camera, light, and microphone first.

Clear your desktop, because the coding rounds use screen sharing.

The onsite day can be virtual or in person. HRT states that it prefers at least some of the onsite rounds to be in person. For an in person day, wear business casual: a shirt with clean trousers, or a simple dress.

A suit is not expected at a trading firm. Expect sessions one after another, so bring water.

How to Prepare

• Learn the rounds first. What is the Hudson River Trading interview process like lists each round and what it covers.
• Pick one language and use it in every round. HRT lets candidates choose C++ or Python, and TypeScript with Python for fullstack roles. Practice writing and debugging in that one language. Grokking the Coding Interview drills the patterns behind test problems.
• Practice talking while you code. HRT asks candidates to explain their thinking, name their own mistakes, and say when they need a moment.
• Prepare the design and fit rounds too. The onsite includes design discussion and team fit. See the HRT system design interview and top HRT behavioral questions.
