Amazon Senior Software Developer interview questions

I had 2 Phone interviews followed by an Onsite interview. The phone interviews were straightforward, involving standard questions such as how to reverse a string. Also some questions on arrays, how to find if there are duplicates. Then there were questions related classes and polymorphism. Afterwards I had to email solution to a dictionary problem within the next day, which made use of STL data structures such as hash maps. The onsite interview was a pleasant experience. The hiring manager wanted to know my ambition and what I see myself doing in the team. The staff was a mix of strict interviewers who were opinionated and those who were open to my view point. I did not get good read of whether they were happy with my answers. I thought the interview went positive, however it came back negative.

1. phone screening, casual 2. phone screening, somewhat technical and short 3. code screening via online editor and phone 4. all day on site interview Their interviewing process is rigorous. They do a lot of screening before you spend any time face to face. I think this is a good method, as it weeds a lot of people out before-hand. Stressful though!
