Booking.com Software Engineer I interview questions

The whole interview process was great, I really enjoyed it. At first, I received invitation for phone interview and assignment - 4 not difficult tasks for 1 hour. Next stage of interview process was a phone call from HR: he described details of nearest phone interview with IT specialists and other common things and answered all my questions, I told about my skills and experience. Next stage - remote interview with IT specialists. There was 2 not difficult tasks, interviewers watched for coding process live and I described my thoughts and ideas. Next stage was in Amsterdam, Booking.com arranged flights and accommodation. There was 2 rounds of technical questions and 1 business question. Tasks wasn't difficult again, but there was not only 1 solution, interviewers interested in my thoughts and the way I chosed for solution.

Brief explanation on the company, they presented their requirements and the role in discussion. There wasn't much of details provided, it all was bit general but still gave enough clue on what's the position require.
