Pros
The Lafayette office still has a small-company feel, as projects and teams are small. Most of the current employees at this location are from the Abacus and Online teams. During busy times, food is often provided for client-support roles, and also for anyone having to work outside of normal business hours for special projects or events. Lots of opportunities for community-service involvement, including charity fund-raising events, and Habitat for Humanity (for which the company will pay your time off).
Cons
Now a very large company, composed of many different divisions which were formerly separate companies that Epsilon has acquired over the past 8 years. The result is that corporate-level integration of communication and IT infrastructure isn't fully baked yet.
