I applied in-person. The process took 1 day. I interviewed at Toxic Use Reduction Institute (Lowell, MA) in Sept 2014
Interview
Manager told me the background of the lab, what the lab does, and then let me choose if I wanted to work there. I got a tour of the entire lab, and then I looked at a powerpoint presentation. He had me print out my school schedule, and I make up my own hours.
