I applied online. The process took 1 day. I interviewed at EEI Communications (Arlington, VA) in Feb 2010
Interview
Friendly people. Interview largely consisted of a series of small exams, which became progressively more specific/difficult as one succeeded in the previous exam. One's performance on the tests determines the type of work one will go on to do, with frequent opportunities for advancement.
Interview questions [1]
Question 1
There was no single question that was particularly difficult, though potential editing mistakes do become increasingly possible as the tests go on.
