Pros
Mapcom does a pretty decent job of conveying a family atmosphere. They provide free snack/drinks for their employees, after work "happy hours" in the basement occasionally, "Popcorn Thursdays", and also provide quarterly company outings. Working with smaller telecommunication companies, the clients are friendly and help provide a family-like feel as well. With the company expanding rapidly, hard work can let you climb to a desired position quickly, but the ceiling there is very low. A vast majority of the people there are an absolute joy to work with, and I would consider them the biggest "Pro".
Cons
Where to begin? The average salary there is laughably below market value to "keep you hungry". Once you have proven your worth, you get small bumps but the pay gap is "made up in bonuses". These "bonuses" can come anywhere from 1-6 months later than the original dates, and almost always come in disappointingly low (not to mention highly taxed). You are penalized if you work "only" 45 hours a week (It's an unofficial motto that "This isn't a 40-hour-a-week job"). The job becomes your life, and management honestly wouldn't want it any other way. Upper management is filled with "Yes-Men" and if you voice your concerns/criticisms you will be shunned and reprimanded. You are expected to work occasional weekends in support with no extra pay or comp time for your weekend shift. Support is terribly run, unorganized, and a majority of the support techs are either told to put their focus on areas of weakness or not trained properly at all. You will get burned out FAST.
