I applied online. The process took 4 weeks. I interviewed at Amazon
Interview
It is a 1-round machine learning breadth interview. I was given a real machine learning problem and asked which model, loss function and parameterization to choose. Nothing very deep about my research.
Interview questions [1]
Question 1
Which loss function you'll use for a N-way classification problem?
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.
