T-Mobile Customer Seevice Representative interview questions

You had to take a "test" where they used a system that imitated working at a call center and you have to make at least a 60. Then, went for a "day in the life" where you learned more about the job, then set up for 2:1 interview. Was offered the job and the day before training they informed me that I had a typo on my application that caused my background check to come back with a warning message and the revoked their offer.

I filled out the application online, got a call the next day for the phone interview, filled out the background check, and go in for the face to face interview tomorrow
