Very Fast. Applied and received a phone call from a corporate recruiter within 1 week. I had my interview the following week and second interview shortly after. From applying to the offer letter the total time it took was 1 month.

Live interview was pretty straight forward. People at the office in Vienna, VA were very friendly and accommodating. The HR person who set up the interview was not interactive at all; did not return phone calls. All correspondence was done via email. ( If I did not know the company, would not have gone to the interview....he made it seem very "fly by night")
