Booking.com Machine Learning Engineer interview questions

First round Leetcode-style interview: Prepare for graphs and trees using Python. Second round focuses on system design, followed by HR discussions. Key prep: algorithms, data structures, design. reviews machine learning concepts and pipelines.

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.
