I applied through an employee referral. The process took 2 weeks. I interviewed at Spark Experience (Rockville, MD) in Jul 2013
Interview
Met at a coffee shop for chat about background. Then had a take home programming task to complete in an hour. Was told less than 10% interviewees even knew how to get started on the programming task. Study wordpress and how to make themes. It's almost the only tool used for development.
