I got in through a referral. Had one phone screen with simple behavioural and motivational questions, one Hackerrank-Challenge (75min) and one technical phone interview. The hackerrank challenge was pretty large and not feasible in the time frame, but that was not the goal behind it. The technical phone interview was really easy and focused on coding style. Then I was invited onsite: Well organised trip and very convenient stay in London. I did 3 technical interviews before lunch (problem decomposition, technical question, coding question). They were all advanced but not too difficult. The interviewers gave hints and the atmosphere was nice. After lunch I did a Hiring Interview with 2 Hiring Managers. 30 min behavioural questions and one technical one. I was really happy with the whole process. Unfortunately I was rejected. Interestingly they were really happy with my technical skills, but didn't like some answers to the behavioural questions. Thing like: Not good enough reflection on older projects and lack of motivation for the company. This I do not understand, because I talked a lot about my motivation (which was real ;)) and about different projects. So I don't know what to change on that end. But interesting to know that they put such an emphasis on that.
