I applied online. The process took 2 weeks. I interviewed at PALIO (New York, NY) in Apr 2016
Interview
I met with the Director of Technology and the Senior Developer at that time. Both were really pleasant interviewers and mostly just went through my resume and asked about my different experiences and skills I had listed. They also took a look at a few sites I had built.
Interview questions [1]
Question 1
What interests you about working at an advertising agency rather than a software company?
