Amazon Software Development Engineer interview questions

3 online technical questions. the first one was two find the error in the code and fix it the second was to solve to coding problems and the third was a situation test

I interviewed for a developer position in Cambridge (UK). The on-site interview consisted of 4 rounds, each with different people -- engineers and managers. Each interview lasted about an hour and was divided equally between behavioural questions (based on the company's so-called "leadership principals") and a technical problem that I had to solve on a whiteboard. One of the technical questions revolved around system design, the rest were typical programming / algorithmic problems one would expect at software engineering interviews. My overall experience was neutral toward slightly negative. While about half of the interviewers were really friendly and approachable, the others came across as arrogant or bored. In the end I did not get an offer, but even if I did, I'm not entirely convinced that I would have wanted to work with some of the people I met throughout the process.
