T-Mobile interview questions

I put an application online, recieved an email a day later to come in to "a day in the life" which is basically a tour of T-Mobiles call center & you get to sit down with Customer Service Reps listening in on how they handle daily customer conflicts. At the end of the tour if you beleive T-Mobile is the place for you, you get to scheduale an interview. The interview last about 45 min to an hour which is a 2 on 1 interview. All the questions they ask they want specific events that have happened in previous jobs, you have to explain in specific details. At the end of the interview they say they will contact you regarding their decision, I got an email 30 min after getting home requesting me to fill a background check application using HireRight. After a week HireRight verified my background T-Mobile called me with the job offer.
