I applied online. The process took 2 days. I interviewed at Potomac Partners (Bethesda, MD) in Jan 2015
Interview
Casual interview, you will meet every member of the team so they can get a feel for your background and if you have what it takes to be successful in this environment. You would meet with the two Managing Directors first, if that goes well, you will have a second interview to meet the rest of the team members.
