About 2dbi

Most interview question lists tell you what to study. They do not tell you who asked it, in which round, or at what level — which is the difference between preparing and guessing.

Every question carries its evidence

A question here is not a standalone puzzle. It is attached to the interviews it actually came up in: the company, the stage of their loop, the level being hired for, and roughly when. That is what the filters run on, so “Google, bar raiser, senior” means a question asked in that round — not one asked at Google and, separately, in some bar raiser somewhere.

Where it comes from

Three places, and each one is reviewed before it appears:

• Interview experiences written by people who sat the loop. We extract the questions from them, so one writeup fills in several.
• Individual questions submitted with the context they were asked in.
• Public posts we collect and curate. The original is always linked, so you can check.

Nothing is published automatically. A curator reviews every submission, which is slower and is the reason the corpus can be trusted.

What it costs

Nothing. Every question, experience and compensation report is readable without an account. Signing in only exists so your notes, bookmarks and contributions have somewhere to live.

Help

The corpus is only as good as what people put into it. Adding what you were asked takes a few minutes and is the single most useful thing you can do here — and if you searched for a company we do not carry, telling us is what gets it added.
