Rust: HFT Interview Preparation Guide
Description
# About This Book
Most interview prep books are written for people with months to spare.
This one is not.
This book was written for a specific situation: a performance-critical full-stack role, Rust on the hot path, Next.js on the trader-facing side, and less than 48 hours to prepare. The pressure was real. The stakes were real. The preparation had to be surgical.
What you will find here is not a survey of Rust syntax or a catalogue of framework features. It is a structured approach to preparing under time pressure — how to read a role correctly, how to inventory your actual strengths, how to close gaps fast, and how to perform coherently when the interview room is not forgiving.
The book moves in five acts.
**Reconnaissance** covers the hours before deep work begins: reading the role like an operator, mapping your current position honestly, and building a timed plan that does not collapse under pressure.
**Rust Core Discipline** covers the concepts that come up in every serious Rust interview — ownership, borrowing, lifetimes, traits, error handling, and memory behaviour. Not as trivia, but as reasoning tools.
**Concurrency, Async, and Performance** covers the territory that separates junior from senior in a systems role: async execution models, contention, lock-free patterns, profiling, and benchmark design that holds up under scrutiny.
**Full-Stack and System Design Rounds** covers architecture under pressure, trading pipeline design, SQL that goes beyond CRUD, and the API contracts between a Rust backend and a Next.js frontend.
**Interview Performance and Offer Decision** covers the behavioral round, the live-coding session, the questions worth asking them, and what happens after the handshake.
Each chapter is short by design. The goal is not to be comprehensive. The goal is to give you the right frame, the right vocabulary, and the right level of confidence for each topic — quickly enough to be useful.
If you have more time, go deeper on the chapters that match your weakest areas. If you have less time, follow the two-day plan in chapter five and trust the sequencing.
The interview is not a test of everything you know.
It is a test of how you operate when the stakes are clear and the clock is running.
That is a trainable skill.
This book is the training.
