Overall the interview process is as follows:
a) Craft Interview 1 (60 min via Zoom) with an on-the-spot business case
b) Craft Interview 2 (60min via Zoom) with a pre-prepared business case (a brief sent in advance)
c) Cultural Fit Interview (60min via Zoom)
I got to the Craft interview step. I got interviewed by 2 Senior ML engineers, one of the 2 was very unpleasant and appeared rude from the first minute of the call, laughing when I was not being too precise in my answers, at times even looking at the colleague laughing. VERY UNPROFESSIONAL. This put me off and I couldn't perform properly. Nevertheless, I decided not to hear the feedback from the HR as that gave me a spark of company culture and I didn't want to waste any more time with them.
To be honest this was the best interview experience I ever had. All interviewers were super nice, questions were interesting, and they provided a detailed feedback of all interviewers at the very end. I did not get an offer though.
I interviewed at Booking.com (Amsterdam) in Mar 2024
Interview
I applied online, they sent me a hackerrank link with one coding question and 9 multiple choice answer questionnaire about machine learning topics. The coding question was the top k hotels question but in the leetcode example there is no punctuation marks in the input. So you need to be carefully read the question, it seems the same as the one you google it, but with a small trick.
