I applied through an employee referral. The process took 4 weeks. I interviewed at Booking.com (Amsterdam) in Dec 2018
Interview
I applied to Booking after a referral from a data scientist.
Firstly there was a very easy phone interview with a recruiter, where I basically went over my background. Afterwards I had I phone interview with two members of the data science team, where I had to present a business case I worked on in the past, and solve 2 business cases with them.
The last part of the process consists of half a day of interviews. The most important part of this are two interviews that follow a similar pattern as the phone interview.
The difficult part of the interview is that you can be asked a very wide variety of problems that a data scientist can encounter. If you've already worked on something similar, then you will probably be fine, if not, the data scientists will give you hints but of course this will count against you and you also have too much time in your hands. Also, they are looking for people that will ace most of the business cases (3/4).
Interview questions [2]
Question 1
How would you measure the impact of introducing a new tool for partners?
I applied online. The process took 3 months. I interviewed at Booking.com
Interview
Interview process was solid and relevant. There were three rounds: one technical, one business case directly tied to the role, and one focused on company alignment. Most rounds included case studies, which tested problem solving approach along with technical knowledge. The conversations were clear and to the point. Main focus was on how you approach problems and whether that fits with the company values. Reading about the values and culture beforehand is important
Interview questions [1]
Question 1
Follow up questions from case study, questions about experimentation
30 mins phone screen with recruiter, next round will be with 2 data scientists and discuss on a business case. Seems like they did have some opinion on that question, it was not like a open discussion.
I talked with manager and recruiter. Some questions about personality and some about technical skills. Some were more difficult then others. The people were quitte nice. But a lot of competition
