Booking.com Graduate Software Engineer interview questions

The process is quite smooth. First round was an general online assessment of 4 questions consist of 2 mcqs and 2 code. Then there is a cognitive test. No further response after that.

First I applied and got an Online Assessment of 3 questions related to hash maps, strings and heaps Then I passed it, and I reached a phone interview with the recruiter. The recruiter was so friendly, and explained the opportunity to me and discussed what I want to achieve with them Later on, I got a rejection email for no reason. If I passed the phone interview, I would have 3 interviews in one day.
