I applied online. The process took 4 weeks. I interviewed at Amazon
Interview
mainly coding + ML questions
They also ask you to talk about your previous research experiences and ask questions accordingly.
The coding question was not difficult but they didn't clarify the question when I obviously took it the wrong way
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.
