Pros
You'll like the people and what remains from the original Resource culture. The new office might be pretty cool when it's ready.
Cons
It is very top heavy, full of narcissists set in their ways of old advertising traditions. But they'll tell you how they're blazing the trail and becoming the agency of the future. Each day is a grind as you're micro-managed, told what to do and how to do it. Mindless creative is churned out around you and lauded as setting the bar high in the industry. The only inspiration you'll get is from the friends you'll make, all of which hate their jobs too. You'll leave, get home to your family and cherish being around people that care about you. Immediately, you'll be sucked right back into the seventh circle of hell as soon as your phone starts going nuts over some stupid issue that can wait until the next day. You'll stay up late, writing Glassdoor reviews to help ease your mind, wake up and do it all again. Once you reach the breaking point and start interviewing elsewhere, prospective employers become disinterested with you as all your skill, drive, and ambition have atrophied under the crushing weight of the megalomaniacs running the show at Resource.
