Pros
Small team. Initially a collaborative environment.
Cons
Dubbing oneself an "interactive agency" would mean that your workers come from an "interactive" background. WRONG. What's Up is essentially an interactive shop ran by leadership that come from the editorial/print world. Additionally, design-by-committee is quite the normal process there.
Lack of professional growth, financial growth, or overall mentorship is prevalent as well. Employees are not permitted to showcase work on their personal sites once they leave, might I add. Lawyers will get involved if your personal site has higher SEO than theirs. You'll be considered a "threat" to their business.
Between long hours and constantly explaining fundamental processes that are normal in other agencies, there was absolutely no growth for my tenure there. Salary-wise, they aren't anywhere near industry-standard for Atlanta.
