Enterprise Mobility interview questions

I applied online and three weeks later I got a phone call from a branch manager. I wasn't able to get to the phone in time but she left a message. She also sent an email and I tried to call her back (within 30 minutes). She never called back or replied. I continued to apply to different locations and a week later an HR rep emailed me about what schedule I'd be able to work and that she had a possible position open for me. We scheduled an interview for the next day at the enterprise closest to me. The interview was with the assistant manager, he informed me about how "enterprise works" and how maybe when I have my college degree, I could continue to work there as a management job. He asked me questions mostly about previous work experience, my experience with customer service (because that's what they are ALL about), and he threw in "Tell me about a time you had to work under pressure" and "Why should we use preventive maintenance on our vehicles". Honestly, I didn't the words out quite right on that one, what I should have said, what that it would benefit the company AND the customer and give examples why. The man who interviewed me was very nice, after the interview he showed me around the garage and where you wash the vehicles and then I was on my way. He told me the HR rep would be in touch with me in a few days and to call the store if I had any questions.
