Great opportunities but Epsilon lacks competitive pay
Pros
Tons of great opportunities, many people are wonderful in terms of wanting to give you the experience that you are looking for. Most people are great to work with and are generally sincere. There's a great team environment. There's too much work and not enough people, so you won't need to worry about losing your job due to lack of business.
Cons
Epsilon does not pay competitive enough for those who are promoted within the company. I've been at Epsilon for 6+ years and was promoted several times, but my pay raise is very low compared to the market rate. I am making less than my direct report and expected to be responsible for many more things than my direct. I do not always feel that I am being compensated for the value that I provide for the company.
