Ray Skillman Auto interview questions

The hiring manager made an error for my scheduling interview and made me wait one hour, having fun with coworkers, before greeting me. She insisted I was lying until I showed her the email she sent to me. She didn't seem interested in anything I said and stared at me blankly the whole time. I believe she was disinterested because I was not male, like the rest of product specialist on the floor. Very unprofessional. Also very insulting.
