Interview question banks

Interview Questions Hub

Real questions and structured answers for 22 top interview surfaces. Organized by company, by role, and by round type — because every interview is actually three things at once.

Honest framing: These question banks are for prep. They’re what to study. Reading them once won’t make you pass — but knowing what’s likely to come up before it does is the difference between candidates who freeze and candidates who don’t. For the live round itself, PhantomCodeAI is the real-time copilot.

By company

Each top-tier US tech company runs its own interview ritual. The same engineer can pass at one and fail at another — not because skill changes, but because the format does. These pages cover the structure, the favored question types, and the real follow-ups.

By role

Different roles, different rubrics. A senior software engineer and a senior data scientist both interview at L5 — but the questions, the time pressure, and the rubric are entirely different.

By round type

Each round type has its own pattern recognition. Coding rounds reward fast pattern matching; system design rewards trade-off articulation; behavioral rewards story structure. Different muscles.

Studying isn’t enough on its own

You can read 200 questions and still freeze on the call. The candidates who actually get offers do both — they study the questions and rehearse the live format. For the live format, AI mock interviews and a real-time copilot during the actual round do what reading can’t.
