I wanted to share my experience with Amazon Phone interview and OA experience.
My OA was very easy, they were 2 questions that were similar to each other both required you to sort some objects. I solved with Java using PriorityQueue 1st Q 23/24 test case (Unknown test case) 2nd Q 7/11 test case (Runtime performance only).
My Phone interview, the interviewer was cool & helpful was directing my answers when he found I am taking a wrong path but unfortunately I failed because I have an interview panic.
It was only 1 tech question which was designing a BinaryExpressionTree class , then create a function to print this tree, then given a string of an expression in a Polish Notation generate the tree from that string. (We ran out of time)
The behavioral questions were: What was your fav project and challanges in it ? Tell me about a time you got out of your comfort zone ?
Finally I would like to know your thoughts about the BinaryExpressionTree question is it tricky ? or it's an okay for an interview ?
