Amazon Software Engineer internship interview questions

Online code assessment + onsite interview. The Online code assessment was similar to other's experience posted. The onsite interview had 2 slots and 1 hour for each. The first slot gave me a chance to introduce myself. Then the interviewer asked me to modify a piece of code to improve the performance. After that, he asked me to tell an experience which a deadline is quite close but I still have many works to do. The second slot is a whiteboard code test and another question of the project experience. In the beginning, the interviews asked about the complexity of some useful data structures. Then the whiteboard code test is a BFS of an array.

It was a video interview. Live code sharing was enabled. There was no need to write whole working code, pseudo code is sufficient. Interviewer was good and was giving me time to think about the technical questions.
