I worked at RPA full-time (More than 3 years)
There is an amazing culture of collaboration at the time that I worked here. There was a good mix of different personalities and teams worked closely together since it's a full service agency.
A few bad apples and bad tempers, but most of those people were weeded out when the Honda/Acura accounts went up for review.
Advice to Management
Keep up the good work,
I applied through a recruiter. The process took 6 days. I interviewed at RPA (Los Angeles, CA (US)) in December-2015.
First met the recruiter at a school portfolio night. Very nice, asked lots of questions, took lots of notes. Sent a follow up email a few days after the event along with a recommendation from a CD who was working at RPA at the time. Heard back from the recruiter the same day and exchanged a few emails. Had a phone interview and that was that.
