I applied online. The process took 3 months. I interviewed at FAA (Alexandria, VA) in Oct 2011
Interview
From the time the job closed to interview, it was almost 4 months. Was asked a series of several "what would you do in this situation" questions. They thanked me for my time and asked if I had any questions. Was told that an offer could take just as long as the interview process did and not to give up.
Interview questions [2]
Question 1
What would you do if you overheard co-workers talking about the new person (or another employee) in the bathroom or breakroom?
