Pros
Friendly atmosphere. Good insurance benefits. Great visibility and recognition from industry associations and anybody working in the Advertising, Research, and Marketing industry. There's always a small budget for training and/or to attend conferences. Some bosses are flexible granting extra days off. Occasional free food due to the abundance of catered meetings.
Cons
Everybody gossips, which presents a lack of professionalism among the work force. If you don't gossip or partake in small talk at some point during the day you are seen as an outcast. There is very little opportunity for growth within departments, raises are non-existent, and bonuses are minimal. There is a lack of middle management, there are many VPs and SVPs who seem to be getting all the perks while the rest of the work force keep running a tight ship, patching more than needed instead of looking for opportunities to innovate. There are a lot of ideas and promises and not enough development or actionable goals.
