The process took 4 weeks. I interviewed at Amazon in Aug 2011
Interview
I was contacted thru email by a recruiter and scheduled the first phone interview. It all went smooth and I got another email saying that a second phone interview has to be scheduled.
The second engineer I spoke to had a very, very bad Chinese accent. I was having trouble understanding what he was saying on the phone. I was like hearing 20% of the words he spoke and tried to fill/guess the rest of sentence. Nearly the whole interview was spent on him repeating the things he said, as I was kindly telling him that I understand nothing. About 30 minutes had passed when he successfully asked his first technical question. It was a really bad experience. I told about this to the recruiter and I was scheduled a third phone interview.
The third one was pretty much like the first one. Straight technical question. I did pretty well; analyzed the problem, thought it through, spoke out loud, came up with an efficient algorithm, checked for corner cases, commented on the running time and space complexity and mentioned other possible ways of doing it. I thought I aced it.
I sent an email to the recruiter after a week. He didn't reply. Another after a month, he didn't reply. After 3 months, I got an automated e-mail saying I was rejected. Not very positive for the HR of Amazon...

It was a 2-3 round process, depending on how your interview went, with increasingly hard DSA questions followed by some HR and behavioural questions. First round was mostly easy and medium leetcode, followed by medium and hard questions in the second round and above on more complex topics.
I applied online. I interviewed at Amazon (Bengaluru)
Interview
The interview process consisted of an online assessment followed by two technical interview rounds and one behavioral round. The technical rounds focused on Data Structures, Algorithms, Java, and problem-solving skills. The behavioral round covered Amazon Leadership Principles and past project experiences. The interviewers were professional and the process was well structured.
