Interview by recuriter, Phone interview over Chime with one easy Leet code problem and 2 behavioral questions. Although the interviewer was very casual at the start of the conversation, it quickly changed into behavioral questions at the start.
Interview questions [1]
Question 1
Encoding optimization algorithm and talk about a project you did recently.
I applied through college or university. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in Nov 2012

Question 1
It was an extended question regarding to binary tree. The tree consists of the numbers and the mathematics operations, like +, -, *, /. The root is the operator and its two children is the numbers. The question is how to calculate the result of the whole tree. I suggested to DFS the tree to reach the bottom. But my interviewer wanted me to use another way to solve the problem. I finally use recursion to solve the problem but it consumed too much time and I even didn't have time to do the second question.
First round is just leet code coding which screens through AI before going into live coding. Pretty simple and straighforward. Not too tough. Recruiter walks through it pretty nicely. Not sure how many rounds there are exactly
After submitting my application for the Software Engineer position, I received an invitation to complete an automated Online Assessment (OA). The assessment consisted of standard coding challenges, primarily focusing on algorithmic and data structure problems. Unfortunately, a few days after submitting my solutions for the assessment, I received an email informing me that I would not be moving forward in the interview process and was rejected.
