I applied online. The process took 3 weeks. I interviewed at Ogilvy (New York, NY) in Jun 2012
Interview
While the folks here were nice, their interview process was strange considering this was a job to be on call for them. At best, it was part-time, yet they made folks jump through hoops, interviewing dozens of folks, as if they were hiring a full-time staff person.
Interview questions [1]
Question 1
Questions weren't difficult, but it was a lengthy process that was not worth it considering the job was intermittent.
