Amazon Software Development Engineer interview questions

Two 45 minuet phone screenings back to back with different engineers. The first interviewer was a bit sharp, and straight to the point. After saying hello he just asked if I was ready and sent me a link to a collabedit so that I could code. He had a thick accent, and was somewhat hard to understand, really seemed like he didn't want to be there. Second interviewer was much more pleasant, asked a few questions regarding discrete mathematics before going into a coding problem on collabedit as well. Once finished he asked for an explanation of the time complexity and if I had any questions.

two 45 minute interviews. first one asked you stuff like time complexity, and to develop an algorithm to find whether two strings were anagrams of each other. second interview had you actually implement the question they asked you. For me it was whether two linked lists intersect. They are very nice and they help you out. They don't expect you to know everything off the top of your head so if you forget the syntax for something, they'll help you out.
