I applied online. The process took 5 months. I interviewed at NJ State Toxicology Laboratory (Newark, NJ) in Jun 2012
Interview
Met with a group of people (all of the forensic toxicologists). Each person asked 4-5 questions ranging from how instrumentation works to basic lab work procedures and experience. If you didn't know the answer they would try to help you arrive at the answer, especially when they ask you how to make certain solutions.
Interview questions [1]
Question 1
How does a GCMS work? What is your experience with it?
