Go into the office. You interview with the recruiter then go for a drug test. They will let you know if you need to come back for training. Very casual.
I applied through a recruiter. The process took 4 weeks. I interviewed at Jennmar in Oct 2015
Interview
Phone interview which was around 30 minutes, very thorough of my education and experience and applicable skills. questions were very heavy on Business Intelligence, methodologies and things of that nature. The gentlemen who interviewed me was very nice.
