Amazon Software Development Engineer interview questions

It went good but unfortunately I couldn't able to crack it. Interviewer was very friendly and polite. Overall it was a great experience. There were actually 2-3 technical interview rounds.

The interview process had 4 rounds First 2 we're the technical rounds which contains coding questions of medium and hard level. This round also includes some basic introductory questions. The next round included questions on Resume and leadership principles of Amazon. The overall experience was good however there was a huge gap of 1.5 months between my 1st round and 2nd round due to which at a point I stopped my preparation. This process can be done quick by Amazon.
