Process
First, HR will contact you, then if you are a good fit, an hour of technical round interview with 2 engineers from the team. They focus a lot on the math behind ML, including the derivatives of loss function and chain rule. Be prepared to be interviewed by PhD students who care a lot about the theory and not the actual technical skills.
