VO after 3 rounds of OA. The interviewer is nice and it is not so hard. We first discussed about my previous experience and then we have a coding question. Finally, he asked me about hashing.

Interview
After applying on the Amazon jobs website, I was approached via email by an Amazon recruiter. They set up an online assessment for me, which were two coding questions in 90 min as well as 15 min survey asking you to explain your thinking for the coding questions, and a survey with personality questions (strongly agree, agree, disagree, strongly disagree).

Question 1
A technical coding question included a question about binary trees and the various traversals (In-order, pre-order and post-order). If given the In-order (L, M, R) and Post-order (L, R, M), can you return the original tree? (M for mid instead of root because it starts with R). The two inputs are arrays of integers, the values at each node of the binary tree.
