Booking.com Developer interview questions

There was first a phone technical interview with two medium questions. The first one was to find if two words can form another word from a dictionary and the second one to get a list of files from a file system hierarchy. Afterwards I was invited to a onsite 3-round of interviews. The first one was coding a solution to the problem described below, the second a system design session to discuss the ways to create a Booking feature and the last one with a team leader about cultural fit.

At first there was a relative simple set of question and a single coding interview. After that, one or more technical interviews with senior developers and the hiring managers. Every one was kind and genuinely interested in their work, and always giving back great feedbacks.
