Every title here opens the real problem on TrueInterview — a runnable workspace and a server-judged verdict, not a screenshot. Synced from the live catalog every hour.
Counted from the whole bank rather than claimed: which formats and companies have been reported this quarter, which questions turn up at the most employers, what the difficulty and topic mix actually is. Recomputed hourly, with every share naming the population it is a share of.
Last 90 days: 154 sightings at 46 companies — Algorithm 70 · SQL 32 · System Design 28 · Low-Level Design 18 · AI Coding 6.
Reported most: Amazon (23) · Google (16) · Meta (12) · ByteDance (9) · Figma (8) · Apple (7) · Snowflake (7) · Microsoft (5)
Asked at the most companies: Design News Feed (16) · Design Job Scheduler (14) · Merge Intervals (14) · Design Notification System (12) · Minimum Meeting Rooms (12)

Interview process: How 82 companies interview, round by round (334 guides) · the same guides by topic
Round-by-round writeups: the recruiter screen, the hiring-manager round, the culture interview, the project deep-dive. Read the loop before you practise for it — each company's page carries its guides above its questions.
What candidates say happened in the room, written up by the people who sat the loop — the freshest thing here, since a report lands the week the interview happened.

The newest slice, not the bank — use the navigation above for the rest. Every question is on a company page, a format page, and (if it carries a sighting date) a month page.

| Live API | what this repo is generated from |
Everything under companies/, formats/, by-month/, guides/, insights/, free/,
experiences/ and data/ is generated hourly by scripts/sync.py from TrueInterview's public, documented,
read-only catalog API. That API publishes metadata only — a title, a company, a format,
a difficulty, a sighting month, a URL. No problem statements, no solutions, no test cases,
and neither does this repository: what you get here is the index, and the questions
themselves live on the site.
python3 scripts/sync.py # refresh from the live catalog
python3 scripts/sync.py --check # verify nothing is stale
python3 -m unittest discover scriptsDesign notes, the byte budgets and the rules the renderers hold: DESIGN.md.
Sightings keep this current. Report a question or fix a row — read CONTRIBUTING.md first. Short version: a summary in your own words, never a screenshot or a copied problem statement.
The tracker — these scripts and the index they generate — is MIT (LICENSE). The questions and guides it points at belong to TrueInterview and are published on the site under its own terms.
