Delta Plastics interview questions

A accounting rec. service who reached out to me. The interview process started in early December and didn't end until late January. First I went to the rec. agency and they proceeded to get me a phone interview. Once I passed the phone interview I was called into the CEO to meet and then was given a written math test to show if I can without a computer or calculator solve a written case study and show that I know what a profit margin is and how to manually conclude percents. I was applying for a customer service manager position/sales - The CEO simply spoke about himself told me he had children, wife, and was born in SLC, UT. then he asked me to tell him about me. Then he left and the current manager handed me the paper with the test. They both kept asking if I had questions but didn't really ask me any questions. I felt is was a very strange interview. I have several years experience in management. I told the rec. agency about it, and the next day they told me I wasn't a good fit, told my rec.agency I dressed badly, and several other inappropriate untrue remarks. I have never been so offended by both organizations. I would never recommend either of them to anyone. I had worn the same outfit I wore for the rec.agency, and several interviews. I do dress very professional and my family and friends assured me that I do and did dress well and I would have thought if I dressed badly the rec. agency after meeting me would have not pushed me further in the process. I warn you.. this company is STRANGE!
