I applied through a recruiter. The process took 2 weeks. I interviewed at Epsilon (San Francisco, CA) in May 2017
Interview
Met with six people, five in person and one via video. Straightforward questions about experience, focusing on dealing with difficult clients (which gave me an indication of what the position would entail!) Recruiter encouraged me to wear a suit, and I did, but I could tell that it was out of place.
