Booking.com Developer interview questions

Very smooth with quick feedbacks; Learnt a lot and they were very helpful and friendly. The phone coding interviews are slightly easier than the actual in-person interviews. At the in-person interviews focus on applying whatever you learnt. Don't try to do every single hackerrank or leetcode problem and expect to do well. Apply all that knowledge! Know exactly why you choose a certain data structure...is it more efficient for reading or writing? how much space will that Data structure you chose take on disk? if i chose a key value store then what will my keys be? can i add more information in the key to make lookups faster? Also another tip: Don't overthink and complicate the answer. Simple answers sometimes are the best way to begin solving the problem
