CenterPoint Energy Customer Service Associate interview questions

I applied for the Associate Customer Service job in June. I received an invite about a month later requesting an interactive interview. This was pretty cool. About three weeks later I was contacted via phone to set up an in person interview. The in person interviews was in a large room with other candidates waiting to be interviewed. There are about 8-10 Centerpoint employees, two per room, waiting to interview with you. My interviewer was RUDE. He had a very condescending tone. It's a call center, customer service job, not quantum physics. I answered the questions clearly and leveraged some expertise I had acquired from a similar industry to answer my questions in STAR format. He was clearly intimidated by me and for no reason I could think of. If you want this job be ghetto and dumb it down!

Applied online on Aug 2015, received an invitation to do a video interview on hirevue, did the video interview and a week later on 8/31 received another invitation for an in person interview, did the face to face interview Friday September 4, 2015. Currently waiting to hear a response, overall it was an amazing experience interviewing with great down to earth recruiters. It was more like a get to know you process rather than an interview.
