Google

Live coding: implement two functions. Make sure you know DFS well. Ask plenty of questions, because only a vague description is provided. They want to actually test how you gather requirements. They asked me if it's my first interview at Google.

Friendly staff. Nobody in the working areas. A lot of perks, including dinner. Nice environment. Mostly coding in algorithms and discussions on algorithms. Some mathematical questions and great lunchtime. Trees and hash tables.

The interview process began with a phone interview, followed by two interviews at a branch office conveniently located near my residence. Subsequently, I underwent approximately five interviews in a single day at the main office where I had applied.
