T-Mobile interview questions

Initial phone interview went well. Meeting with recruiter started off well, but slowly went off the cliff. Numerous questions were asked about handling employee situations in a retail environment (which I had not been a part of since college--20 yrs. ago) Think they were looking for someone closer to the age of what is perceived to be their target smart phone client. Mentioned that I use Mac & PC, as well as Blackberry, and was also T-Mobile client. Got the don't call us we'll call you handshake and I knew nothing would become of it. Whenever, I visit a T-Mobile store to check on new phones or accessories, I look at how the stores are run and see why they are being purchased by AT&T.

I had a phone screen and then 6 1:1 interviews 2 weeks later. The interviews were back-to-back and I thought they went very well. I stumbled on one question: If you worked for a TV manufacturer and had to build a better remote control, how would you proceed? I forgot to mention that I would seek input from users/customers.
