Robb Report interview questions

I had a 1 hour interview with the hiring manager and 30 minute interview with his manager. Then I had a 30 minute follow up interview with same person and and an additional 30 minute interview with someone higher up. I was told I’d hear back by end of week or early the following week, but I was completely ghosted. I didn’t speak to HR until midway through the process ( at my request) and I’m not sure we were on the same page salary wise, but a follow up email regarding my status would have been nice given all the time I put into this.
