Amazon SWE Intern interview questions

One debugging challenge, one offline coding challenge, and one video call with technical and behavioral questions. The video call technical question was not difficult, but I felt like the interviewer was pushing me towards one solution that I was less familiar with compared to another one.

The interviewer started by asking about runtime analysis, big O notation. Then he asked a bunch of graph algorithms such as Kruskal and Prim. Then asked me about projects on resume. Asked one behavioral question and then asked me to write pre/in/post-order traversals using iteration.
