T-Mobile Manager interview questions

Couple interviews on separate days. First with direct district manager, the manager you will report to and be your district manager. Then with at least 1 or 2 other district managers from a neighboring district. Then the final with a regional director.

I got a random call and had a "screening". All I was told was to "answer these questions via email ASAP". After, I was scheduled three rounds of interviews, one with the hiring manager, one panel interview with 4 stakeholders that took up half my day, and the final with the senior director. All those interviews were scheduled without asking my avails and just sent an email letting me know when they were scheduled. I did well on all rounds. Got an email from the recruiter letting me know they were finishing up interviews, and I would get a decision a week later. I ended up getting completely ghosted. I followed up twice with the recruiter, and never heard anything. I'm just frustrated I spent so much time interviewing and couldn't even get a respectable rejection.
