Booking.com Software-ontwikkelaar interview questions

There was a brief phone screening with an HR when I was asked to explain my motivation, background etc. After that I had a technical screening interview. As a preparation for it I got 4 programming questions (data structures & algorithms) which I needed to submit before the actual interview. The phone technical screening interview itself was held by 2 SW developers who asked 2 technical questions (which I needed to code in their environment real-time) and one business-related question. Last round was basically the whole day in house, 3 interviews. The first interview was a technical one, usual things like coding a solution for a tough problem on paper. The second one was a system design interview (but anyways the guys asked me to code some stuff in the end and I was happy to do so :D). The last one was with a senior manager and was more of a chat, although I have no doubt I was somehow evaluated during this chat. Overall: really nice people and smooth interview process, Booking.com is also quite flexible - they changed the time of the interview when I told that I have another competitive offer. A great overall experience!
