the interview was very informal (which he said before we started) and there were no competence questions asked. It was more like a conversation about working there and a bit about me. I'm not sure how to take this. Could it possibly mean they decided the outcome before I even got there?

Scheduling process was very streamlined. There’s a zoom interview first with a general recruiter. The second interview is with managers of the department that you’ll work for. When I interviewed with the a couple of the managers, the questions were easy. They asked about prior work experience and basic camera knowledge.
