I have been working at Kaydon full-time (More than a year)
Most of the staff was friendly and helpful.
Production Super had a poor attitude towards quality...he made it us and them and the associates could see it.
I applied through a recruiter. The process took 2+ months. I interviewed at Kaydon (Sumter, SC) in January 2014.
They are pretty laid back. If they think you are someone they want to pursue they will pursue you; however, overall they lack a sense of urgency within their hiring framework. I met with two people for the first interview, an HR manager and an Operations manager. They were very friendly and helpful. For the second round of interviews, I basically met with everyone in the office and plant on the managerial side. It was a long day of several interviews, but none of them were hard or stressfull.
