First stage was a programming exercise that could be done at home - rather tricky, but very fun to work on.
This was followed by on-site interviews, which lasted ca. 4 hours with 3 interviews in total, each led by 2 people. These mostly focused on technical questions, testing both a broader understanding of programming principles, as well as some more in-depth questions. The questions were fair and well thought through; each solvable rather quickly in principle, but allowing for different approaches while leaving room to explain one's thought process behind whatever approach was taken; and presented in a way that would allow the interviewers to give certain tips to formulate a solution, rather than strict "do or do not know it"-questions).
Feedback after the interview was given within 3 working days.
All in all, a tough but very enjoyable experience - which is quite a rarity to say about any job interview.
