I applied in-person. The process took 1 week. I interviewed at T-Mobile (New Rochelle, NY) in Jun 2015
Interview
Very simple and general, either they will hire you or not. I believe anyone who shows outstanding discipline and enthusiasm will be hired, even if it is clear they are faking it.
Interviewing was easy, interviewd with 2 people, hiring manager and distract manager, after that sent in my BG check, after about 4 days got accepted, started my training about a week later, training takes 2 weeks 10-3pm, on the last day of training you have to pass the initial roleplay and if you don't pass it you will be automatically terminated.
