Booking.com Data Scientist interview questions

Very professional but quite an extensive process. Very lengthy business cases. I had a call with the hr, followed by an hour long phone interview with business cases, then a personal round with 4 business cases and finally a call with senior management. Was not so happy with final feedback since they basically brushed me off as not being technically good enough after having cleared almost all the rounds

I applied on the company website. First step was an online test (entry-level data science/machine learning questions) after which I was contacted by HR for a phone interview. Quite typical experience, why you want to work in booking.com, salary expectations, brief presentation of the position and a few clarifications about my past experience/projects.
