Amazon Software Developer interview questions

Multiple phone interviews with mostly technical questions. Questions are pretty broad which include OOP, Data Structures, UNIX commands etc. in a 45 minutes session. They also asked about the details of programming language such as Java compilers and VM. The use of collabedit is common and any programming language can be used to solve the problems.

I was contacted by an Amazon recruiter via LinkedIn. I interviewed with them previously (unsuccessfully) and looks like they had me in their database. The recruiter told me that they have a hiring event in LA and if I am interested, I can try. Of course I was interested. I have been obsessed with this job for a very long time. I failed once, but I learned a lot since. I decided to give it a try. The event was in three days. Sure, I read up on some algorithms, but there is not much one can do in this kind of time. What I knew would have to be enough for success or failure. They interviewed people in the hotel in LA. You get a separate room, and interviewers walk in, and each one of them gets about 45-50 minutes with you. They ask some theoretical questions (for example, design some classes for a chat system) and some whiteboard coding. As to the coding, there was a lot of recursion and binary trees. There was nothing extremely hard or undoable, no NP-hard problems I was afraid of. I had 4 technical interviews and one talk with the recruiter. The interviewers were great - friendly and pleasant. I got through without glaring errors or missed questions. But I feared that I was not brilliant enough for them. I was right.
