I applied online. The process took 4 weeks. I interviewed at Lawrence Livermore National Laboratory in Mar 2015
Interview
got a phone call from my mentor asking about my resume
he said he had a few more candidates to call but would get back to me as soon as possible (which he did)
I had competing offers and he was very patient in letting me make my decision
Had to submit a drug screen and a background check -- HR was prompt in replying and setting things up for me
