Amazon Software Development Engineer interview questions

Onsite at Houston, there were 4 technical interviews in front of a whiteboard. Good mix of questions. Got a call back saying that the bar raiser thought I'd be good for a management role so I did a phone interview for that but I had a very hard time understanding the interviewer because of his Indian accent. I found a decent solution to the programming question in that interview but was told I was not going to be offered the management position but would be offered an SDE position, the recruiter talked about compensation but would not mention a base salary, only total compensation package, which is fine, but I make my decisions on my known budget and if I can afford rent in the location. Then I heard nothing for several days and was finally passed to another Amazon recruiter. She said that I had a phone call with a team manager to see if it was a good fit, she specifically said it would not be technical that I had allready passed all that. The phone call started out with very bad feedback, the interviewer was using some software that made an echo of everything I said. It was very disorientating to be talking about my past projects but hear my voice repeat. He turned whatever it was off then then drilled into one project in particular in an area that I had said I didn't setup. Then asked an algorithm question, which I found a medium level solution for. It was very adversarial feeling. Very strange company that they state that hiring is there number one focus. I think not hiring is really there number one goal, because after that call the recruiter said she was confused by what happened as well and said she'd try me with 2 more teams for a fit. It's been 4 days since she said that so I've pretty much written them off. No one that I've talked to seems to be a decision maker, if a company makes a verbal offer and says over and over that they want to hire you, why not just finalize it and figure out placement later. Company seems great if you know what your getting into, but the hiring process seems convoluted.

First round was the coding round,in which there were 20 Mcqs asked along with 2 coding questions. One of the two coding questions asked was pretty basic while the other was in the difficulty range of Medium-Easy. The MCQs asked were from Algorithms, OS, Aptitude.
