T-Mobile Customer Seevice Representative interview questions

I applied online in early March. I completed a long, very redundant series of assessments and received a call from a recruiter in VA 3 days later. I was invited to set up an initial phone interview, which I did, and that was brief but went well. Phone interview was basically an informational session that ended with the recruiter asking to set me up with a face to face interview. I went to that interview a few weeks later and really enjoyed the experience. My interviewer was easy to connect with and I felt that it was a very good interview, one of the best I've had. I was told that I would receive a request for a background screening and that it would take about a week so they would call me with an offer if everything checked out okay. I got the email 5 days after my interview and submitted the background info right away. It is now more than two weeks and I have not heard from anyone at the company at all. I sent a very brief email request three days ago for a status update and that email was ignored. I have never failed a background check nor do I have anything in my background that would be cause for concern. I consider myself an excellent candidate with years of experience in the industry, an opinion that was mirrored by my interviewer. I have no idea why they would pass on someone of my caliber and experience or even why they would simply ignore a request to be updated on where they are in the process. Sadly, I found other reviews of this company very helpful and very encouraging but I did not have the same experience in the end.
