The process took 3 weeks. I interviewed at Noblis (Falls Church, VA) in Mar 2011
Interview
Several interactions -- several by phone, followed by meetings in person. The meetings were one-on one. I was known to several in the firm from other work, and there were a lot of backroom discussions about the area of new business that I was interested in.
Interview questions [1]
Question 1
No questions were operationally difficult. The difficulty was answering them in a way that would stimulate their thoughts without being "off-putting".
