I got my interview through university applications. First they ask basic pre-screening questions, then behavioural based on your resume, they tell you about the company and such and then transition into a good amount of technical questions (They don't say in the email). Finally they show you around the OS and what you'd be expected to work on. Also, make sure to prepare some questions to ask ! It's pretty chill, just got caught off guard by the technical questions lol, the interview is nice.
