ARS-Rescue Rooter Customer Service interview questions

I showed up for my interview earlier than my time agreed-upon and they made me wait like another half hour after I was already supposed to be in the interview. Then a panel of three people came into the interview and asked me about my experience. I told him fully about my experience basically went over my resume with them. They asked me some scenario questions and how I would respond one person like my response and was nodding her head and saying yes that's what I would've said. The other two just kept giving me dirty looks. I found out later through a reliable source that after the interview they don't even know me but were already saying he's full of crap and talking really bad about me. If this is how they treat people who don't even work for them yet I would be afraid to work for them and see how they treat me as their employee. Or even worse one of their customers.
