Amazon Software Development Engineer Intern Interview interview questions

Got referred at the beginning of Feb, then reached by recruiter at 2/24 and assigned 2 technical phone interview at 2/27 1. Sent you a Collabedit link before the interview. Introduce yourself really quickly. Given a binary tree with different values on each node, find those values N which N%7 == 0. Why C++ has destruction. Given an int number, return the number of 1s in base 2. For example, 6 = 0000110 return 2. What's the difference between the stack and heap when they are initialized. What's multi-inheritance and why it's bad. 2. Sent you a Collabedit link befor the interview. pow Binary tree level traversal.

2 hour back to back technical interview. You will get a third technical interview if they think you were on the fence. Hashing, data structures, and design questions. They also asked me if i took the algorithms class, then they proceeded to ask me about NP-Complete problems etc. They were very nice overall. I recommend getting a good cell phone reception and internet access before the interview, because my call kept dropping on me during the interview. It dropped at least 6 times during my first technical interview, and I think they weren't happy about it, therefore I was sent to a third technical interview.
