Amazon Software Engineer Intern interview questions

i had only one round and was asked 2 dsa questions only. 1. construct tree from given inorder and preorder traversal 2. Rod cutting Dynamic programming problem. the interview was about 1 hr. I first told approach and then he asked me to write code for both of them. and then asked time complexity and space complexity.

One code assessment on hackerrank, then a one on one code interview with a developer. My interviewer mentioned some worrying things about work life balance, but overall the process was very straightforward.
