USG Insurance Services interview questions

I had 3 interactions - a phone screen, that lead to a phone interview, that led to a virtual interview. The two people that I met with in the final virtual interview were super nice, very knowledgeable, and everything seemed to go well. .....and then not a peep. I didn't ever hear a word about what happened. No offer or feedback of any kind. It was odd because I was in pretty close contact with the manager throughout the whole process. The manager was very open with me and called me (rather than email) during almost every interaction. I believe that I was very qualified for the position - and if I didn't get it, it's no big deal - but it would've been nice to hear yes or no. I didn't even get the system generated "it's not you it's me" corporate email letting me know that they went with someone more qualified. Maybe the manager that I interviewed with left? That's the only thing I can think of that makes sense. I'm not even mad about it (because I took another opportunity anyway) but I wanted to share this warning with anyone potentially interviewing. Keep your options open and follow up as much as reasonable - but I was left out to dry.
