1 HR phone screen, 1 manager phone screen, 1 online coding screen (python), 6-hour onsite interview with various team members: * Open-ended behavioral interview with a graphics developer * Open-ended technical interview with the manager, also a graphics developer * Lunch with a tools engineer and friends, very low-key, feedback not submitted which I really appreciated * Coding interview (language agnostic, I chose python) with lots of helpful feedback, more conceptual than "gotcha" * Machine learning concepts and theory, math/stats arguments seemed to help my case, lots about deep learning architecture and best practices too * Open-ended interview with a technical artist, focused on communication/motivation of ML ideas to people who develop Unity features
