Booking.com Software Engineer interview questions

I Received a mail from Booking HR giving me details of the interview process and brief introduction of booking. Few stories of people working with booking were also shared. For first technical round Skype and etherpad were used. They asked for algorithms based questions and then technical discussion on the solution i have provided. After that Android questions were asked which were related to life cycle of activity, async task, file IO.

1. HR phone screen The recruiter explained the whole process and made some questions about my motivation to apply to that position, about my past experiences and why I've left it and about my salary expectation. 2. Technical phone screen There is some problem solving with code shared in an online editor. Simple question (implement a function to return the first n chars of a text, without breaking any word) with some follow-ups that added obstacles to your solution, so you could explain how you'd overcome them. 3. Face to face interviews in Amsterdam A whole day of interviews: 1 from HR (warm-up, check if something has changed since the first contaxt), 2 technicals (algorithm-heavy) and 1 business-related (behavioural questions and knowledge about the business model).
