Barrows Manager, Studio Operations interview questions

I first spoke with the HR hiring manager for this role on the phone for maybe 10-15 minutes. Pretty basic introductory interview where you're vetted for general job match. I then interviewed with a manager of the team who asnwered all of my questions thoroughly. I felt like the interview had gone great but then I didn't make it to the next round. When I reached out to the HR manager who had been super responsive before she never responded with any reason for as to why I wasn't a good match. Not even a general message. This was off-putting to me a bit.
