Pros
It's a very easy job. You do the basics and you are recognized (not promoted or receive a pay increase). You do get experience working in customer support that looks good on a resume. Give you free software and access to all the websites which is a plus if you are interested in doing your own family history. The guys who work over in RMA are awesome.
Cons
Since it is so easy, it gets boring quickly. The clients are often computer/technology illiterate and it can be extremely frustrating to work with them over the phone (you would think clearing the cache and cookies was brain surgery). Very little opportunity for growth and promotion. There were people who had been in the call center for the better part of the decade in the same position or just one level up. Main reasons why I was yelled at on the phone: Products can be buggy at times, terms and conditions are very absolute but easily misunderstood, and Archives.com is just a terrible site. Also just look through the other reviews. Notice the only ones who rate the company high is upper management.
