Booking.com IOS Engineer interview questions

I progressed through the interview rounds up to the system design stage. During that round, I made a conscious effort to clarify requirements by asking questions and felt that the discussion went well overall. However, the feedback I received was unexpected: the interviewer felt that I did not lead the conversation sufficiently and asked too many questions, and also commented that my design was not scalable. After receiving the rejection, I first reached out to the recruiter to seek clarification or understand if there had been any misunderstanding, but did not receive any response. I then contacted the interviewer on LinkedIn to better understand the feedback. He initially shared what he considered the ideal approach, and I responded by explaining my design decisions and how they addressed scalability. Unfortunately, I did not receive any further response after that. Overall, the lack of follow-up and communication left a negative impression of the process. I do not recommend.
