Very easy, nothing too it. the mgr doesn't really do a very good job of asking detailed question about my skill sets. Very informal, and no real process lined out. No reason to study or dress up to much.

Met their the HR manager at a career fair, and I was invited for a one-on-one interview the next week. Not too much question has been asked by the manager but he did explain a lot for the company, the team and the position with great details. Two weeks later I was at the group interview, and this time they asked some detailed question about my career goal and concern. 15 minutes after the final interview, they offered me the position, 🙌!
