I applied through a staffing agency. The process took 2 days. I interviewed at Boyd Coatings Research (Hudson, MA) in May 2012
Interview
They just basically asked for previous experience as a janitor. Whether or not you take well to directions. They also asked if I would be willing to do overtime if needed and if i'm good with attendance and effort level.

Question 1
I didn't find any questions to be difficult or unexpected. It was a pretty short interview.
