Enterprise Mobility interview questions

A few days after applying, I received an e-mail asking for a convenient time to conduct a phone interview. i replied and received and out-of-office response from the area recruiter but was promptly scheduled upon her return from vacation. During the phone interview I could tell I was on speaker with others in the room as I was asked general interview questions about my resume and work experience. They want to make sure you have an interest in sales with their company and might ask why you're applying based on your major.
