AT&T interview questions

I filled out an application online. A couple days later I had a pre screened 5 minute interview. 2 Days later I received another phone interview. I did well with the phone interviews and was scheduled for a 1 on 1 interview. I was told to dress professional and to bring my resume. When I arrived at the store I meet the manager who was hiring. As soon as he saw me he looked at me from head to toe and gave a displeasing look. I apparently I did not dress professional enough. I was asked a series of questions. Be careful when answering their questions. They are trick questions. Of course I was applying for a sales position. I am a good sales person, but I guess I'm not a shark like what they were looking for.
