The first round was with the hiring manager. It was a nice and open chat about the role, company and my background. The second interview consisted mainly of small standard questions: Attention layer, L1 sparsity regularization, backpropagation, vanishing/exploding gradients, etc. The interviewer just wanted to hear the standard three-sentence textbook answer, no further discussion. I have not heard back from them for a more than a month. The recruiter, which was always quite responsive while scheduling the interviews, has ghosted me and did not reply my requests for a status update.
