Amazon Software Developer interview questions

My resume was found by recruiter from Seattle that applied on my behalf to Amazon.com. Initially everything went pretty smoothly. First interview was phone interview conducted by non-technical person who had a list of questions and wrote my answers. After that they send me coding assignment that I had to finish in 24 hours. This "skills test" consisted of 8 different assignments that required writing the actual code. Some assignments were small and easy and some pretty big and complicated. All in all it was pretty difficult to finish them in 24 hours especially for working person. After they reviewed code of assignments I have been invited to interview event in Toronto. They just "forgot" to mention that interview will take place at 25th floor and that was deal breaker for me. So as a result I didn't show up for in-person interview and got "no-offer".

I got two phone interviews (They are 1 week apart from each other). They considered the fact that my background is not CS. (I'm in EE. but I have experience on system software engineer ) They asked basic questions. All questions are in typical coding interview books. I was called to on-site interview. there were 5 interviews including lunch interview. All questions are in glassdoor interview experience. but I'm not so good to explain even basic things. So rejected
