T-Mobile Retail Sales Associate interview questions

I applied online, the online application also included the assessment test, I received a call within a week, the person that called wanted to interviewed the same day but I couldn't so we scheduled for later day, I'm not an interview type of person first of all, I get really nervous when I think a job is really important to me, that person asked me a various of questions and scenario in which I did horrible at it I might of been in any of the scenarios she gave and did great but I just couldn't think lol I'm very outgoing and talkative but again I'm not good when it come to interviews with scenarios lol the offer was $11.50 Hr with commission on what you sell, the person took a copy of my resume and said will call me back for a second interview with a manager. This job was in Northern New Jersey.
