Enterprise Mobility interview questions

I applied for this job online and received an email back within a few days to schedule a phone interview which was scheduled for the following week. They asked me basic questions such as a time I had to sell something and how I went about it. They also asked me a time I dealt with an unhappy customer and how I dealt with them. A week later I was contacted and learned that I made it to the next round of interviewing; getting a face to face interview at the regional branch which was scheduled but we have not met yet.

Had my first interview with the Talent Acquisition Manager 1:1 at her office. Asked quite a bit about my resume and previous sales experience. I was offered a second interview at the end of this interview with the Area Manager and Branch Manager. This was scheduled for a couple weeks later at a local branch. Went to this interview and was again asked many of the same questions along with the opportunity to see the operations of a branch. At the end of this interview I was offered a third and final interview with the Regional VP of Rentals. This interview was much more difficult, again looking into previous sales experience, but regardless of what I said it seemed it was not the correct answer. I left this interview nervous I would not get the position. A couple of days later I was contacted by the Area Manager offering me a position to start post-college.
