Pros
WKND is incredibly competitive, They don't let anyone work there who isn't the best. I had a culture shock when working there because II was surprised that it didn't operate alot like an agency. The workload isnt "High" It's just really hard. So It can take a long time if your under experienced.
My experience was that I learned a Freaking ton from Grayson Cross who was my boss, taught me more about companies and running media then my last 3 companies.
Hope that I can work with them in the future but I was laid off because I didn't make the mark.
They were really nice about it and Grayson didn't make me feel bad about my skill level and asked me to re-apply in a few years.
Cons
WAYYYY HIGH OF STANDARDS. Hard for anyone to live up to them. Only 2 of the media buyers were considered "Senior Level" and even then they were constantly being taught and told to improve in areas.
