I applied through a recruiter. The process took 4 weeks. I interviewed at theLinktoLearn (Philadelphia, PA) in Nov 2015
Interview
They are VERY interested in both seeing your prior work as well as having you deliver a work product live and post interview. This is an intense process where you do work for them to prove yourself.
Interview questions [1]
Question 1
They went really super deep on my economics knowledge. Get ready to explain everything from the Laffer Curve to Supply Side Economics if that is your area. And then develop educational materials on the spot.
