The process is smooth. Discussed past internship and research experience, followed by one coding question. The questions were very in detail, the interviewer asked many details about deep learning questions. For example, what is adam optimizer, what is transformers (explain in detail), what is the difference between Pytorch and Tensorflow. The coding question is easy, but need to optimize the code. I didn't have in-depth knowledge and experience in deep learning and natural language processing, so I think that's why I failed.

Got a phone interview withing 10 days of applying. The interviewee was some manager. Introduced himself and taked about the company for some 10minutes. Was always encouraging to ask questions. Then asked me about my experience and projects.
