T-Mobile Retail Associate Manager interview questions

I had a hiring manager conduct a preliminary phone interview. About 3-4 weeks later, I received a call asking if I could complete a phone interview later that day. I accepted, and a few hours later completed the interview with two Retail Store Managers. The interview was in STAR format, and she asked me to speak from a "leadership/management" perspective. The interview was easy, just make sure to paint a picture, and give them the result of your actions at the end. A few days later, I received another call form the hiring manager and she said I got the job, she just had to send out a formal offer letter. This took about a week to receive. I received the offer letter and the hourly rate was EXTREMELY low ($13 per hour) along with a base commission of around $11,000 per year. Guaranteed 30 hours per week. I negotiated salary, and they came back with $15 per hour (final offer). I did not accept.
