Amazon Software Development Engineer In Test, II interview questions

Half day interview with 5 people, 45 minutes a piece. Manager, bar raiser, and 3 developers/testers. Technical questions expected to be filled out on a white board (they do take a picture of it). 1-2 questions depending on the time. Don't be afraid to ask for tips and guidance, just not too much. Better not to get completely stuck than to stumble once or twice.

I had 2 rounds of phone interview. In the first round, I was asked to find a unique intersection of 2 arrays. He also asked me Java questions like difference between Abstract class and Interface, can abstract class be instantiated, constructor chaining. I was then asked to give another round of phone interview. The question was to print the nth to last element in a linked list.
