In-person interview. First ask some math questions, such as how many barbers are in USA. You not only need to show your result but also show the process that how you calculate it. Also, show your assumptions. Then, there are some behavior questions such as what is your advantages and disadvantages.
It was a short interview where we were asked basic behavioural questions mostly related to past experiences with software engineering, minimal technical questions. Overall there was nothing really out of the ordinary
