The interview itself was 45 minutes long and over the phone with two interviewers. Only one did the talking and was quite nice. They first described what they did at Amazon then asked me about myself. I completed my interview questions in Java using CollabEdit. Overall the experience was a positive one.

Implement a function that merges two sorted lists into one sorted list
