There were 3 interviews. First, I had a nice phone interview with a senior data scientist. He was very friendly and also we talked about some technical aspects of my experiences but more or less questions were along with my CV. Second, I had a skype interview with two interviewers. There were some probability, business, and machine learning related questions. It was also nice/friendly atmosphere. Then I was invited to visit the office in London to have the final interview. It was similar to the second interview. There were some probability and machine learning questions. Then on the same day, HR called me that I got the offer.

1. Phone screening with a Data Scientist (30 minutes) 2. Personal interview at London office with the Head of Machine Learning and a Data Scientist (1,5 hours) Both interviews were open and stress-free.
