The process consisted multiple rounds. The first one was a phone call with an HR person with multiple general questions about me, my past jobs, etc. It was followed by two rounds of different tests (one written, one oral), then the salary negotiation.

Fairly long application process with 3 rounds. First a chat with the recruiter on the phone, if passed then you are invited to do a test on site which includes a multiple choice language test, and two logical tests, one with calculations, one where you need to describe a process presented on a picture in a written form. Finally a chat with the potential team leaders.
