I applied through university. The process took 4 weeks. I interviewed at Appian (Reston, VA) in Oct 2013

Phone screen which later turned into an onsite interview. Interview schedule was very well planned out - went through about 5-6 in one day. Questions were pretty standard data structures, algorithms, some brain teasers. Interviewers were all very friendly and respectful.
