Polytronix Chemist interview questions

The staffing agency posted the ad on craigslist and I inquired and was interviewed by the Quality Manager and CEO (very small company). The CEO incredulously asked me why I wanted to be a chemist. I received an offer from the staffing agency on a Saturday, rather than during the week - because she forgot - when I was out of town and they wanted me to come in on Monday with no notice. Extremely unprofessional staffing agency.
