Interview
1. Phone interview with recruiter - very pleasant, gave tips and asked what I was expecting.
2. Phone interview with 2 data scientists - asked in depth questions to understand my stats and maths abilities. Good cop/ bad cop situation.
3. In person interview - was the next step but didn't get there.

Interview
The interview process was quite standard just like the other people mentioned at glassdoor. After each round of interview, HR will let you know what to expect next. In this case, you will know how to prepare for following steps. Interviewers are all very friendly. They describe the business problems very clearly and help you get through it. Generally speaking, the experience is very positive.
I applied online. The process took 4 weeks. I interviewed at Booking.com in Sep 2016
Interview
The process was as expected based on their careers website. You make a test which leads you to the first phone interview with HR. After that you get a second interview with members of the data science team. I didn't pass this second stage.
