During the whole process, I was in contact with their technical recruiter, who was very helpful.

I had two technical interviews over Skype and was then flown to the site in Stockholm for an additional three technical interviews in a single day.

I found the technical interviews to be really good; they focused on technical design, coding, and refactoring. There were no trick or memory questions, and no strange puzzles.

The interview process was smooth and quick, and I received immediate feedback after every interview, which I found very pleasing.

Take existing code, point out issues, and refactor it.
