Interview guide

What to expect

Coding assessment

A timed HackerRank-style test with two or three medium-to-hard problems, often mixing algorithms with quantitative or simulation tasks.

Technical screens

Live coding in a shared editor where interviewers probe complexity, edge cases, and how clearly you reason more than whether you finish.

Onsite loop

Five to six rounds across algorithms, probability, low-latency systems, and a strategy game you first solve mathematically then implement.

How ExtraBrain helps

Speed-focused prep

Rehearse timed coding and probability sets, then review local session history to build the speed and clarity Hudson River Trading expects.

Screen-aware practice

Screen-aware context reads the visible code or problem during mock rounds, and live transcription keeps a full record for later review.

Private, local-first review

On-device transcription and local-first storage keep sensitive practice private, with on-device Gemma where compatible or a provider you choose.

Interview guide

Responsible use

Use any live AI assistant only where interview, workplace, school, and platform rules allow it. Do not use generated answers to misrepresent your skills, experience, or authorship.
