Amazon Software Engineer interview questions

I applied online through the Amazon careers site. I was contacted by a recruiter. Amazon flew some of their engineers out to Phoenix and interviewed candidates at a hotel. I had two interviews in a hotel room. The first was pretty reasonable, asked me to implement a singleton and write the code on a whiteboard. The whiteboard was not especially large so it was difficult to fit all the code, especially since I tend to write some code, notice that I forgot something, go back and add a line, etc. The second interview was strange because the interviewer asked me two coding questions and then seemed to be working on his computer while I wrote each answer on the whiteboard. At first I thought maybe he was copying down my code but he did a lot more typing than I did scribbling. He also didn't seem to pay any attention to what I was doing until I finished writing and explained what I had done. Seemed rude and a waste of everyone's time (especially considering I drove 2 hours each way to the interview). We could have achieved the same result by having me just submit answers via email. For the second question, I couldn't fit the entire answer on the whiteboard so I had to erase and continue. By the time I had finished the scribbling exercise there wasn't time to improve my algorithm or discuss anything. I wasn't too disappointed when I didn't get an offer.

Interviewed for Amazon for 3 different positions. Each time, the interviewers we're unorganized and scrambling to find out where to go next. Quite possibly the worst interviews I've experiences
