Process took place at 2014 fall.
First I wrote a test at yandex website.
Than I had a phone test full of technical questions with HR staff.
After that I had a video conference with a technical manager and finally I arrived to Moscow headquarters and had face-to-face interview.
There were 3 people in a room besides myself, all of them turned out to became my colleagues soon.
We had discussed my former background and current intensions.
There were some tricky questions for relevant technologies I have been involved.
