I applied online. The process took 4 weeks. I interviewed at Amazon (Eugene, OR) in Sept 2022
Interview
I had a phone interview after an OA. The interviewer was a senior applied scientist and the questions were 50% technical and 50% on leadership principles. No live coding for me.
Interview questions [1]
Question 1
1) How to approximate pi using Monte Carlo?
2) What is the objective function of a neural network for classification and regression problems?
3) What are the different ML problems?
I was asked basic knowledge in deep learning and machine learning. Also had time of explaining my research. discussed how I can apply my research to the current project. Transformer architecture, bias-var tradeoff, use of positional encoding, long-term dependencies.
HackerRank assessment with solid, fair questions. Communication with the recruiting team was clear and professional throughout the process. I was invited to two additional interviews, one focused on research depth and the other on coding skills.
One phone screen on LeetCode-style medium coding question plus behavioral questions. One loop of three back to back interviews including one round of coding, two rounds of research plus behavioral questions.
