Pros
I began working at MediaMath about two months ago. I had grown somewhat accustomed to a background of micromanagement, high turn-over rate, and overall employee dissatisfaction at my previous job, so working here has been an overwhelmingly positive change, to say the least. I was shocked when my manager told me that I could come in/leave at times that were convenient to me (as long as it was 40 hours a week). At my previous job, someone was waiting for us with a clipboard writing down when we came in. :) Also, at my previous job we were constantly being asked to stay late without being compensated for it. If I ever have to stay late or complete a project during the weekend (which has only happened once) I receive over time pay. (This may depend on your position, though). Everyone has been nothing but helpful and kind. The environment is relaxed, and I find myself laughing with co-workers several times a day. I still haven't had a day where I haven't felt like coming into work. The unlimited paid time off policy is very comforting to have, especially for people who work hard but also enjoy travelling throughout the year. There are also lots of opportunities for growth/advancement in the company. There honestly isn't any work drama (at least none that I've seen) which was a breath of fresh air for me. I've worked in several places where people were constantly bickering/gossiping and it becomes exhausting and annoying after awhile. The cell phone data plan reimbursement and free snacks/keurig coffee are an added bonus, as well.
Cons
I wouldn't say that there are any challenges working here. It probably depends on your position; I'm an executive assistant and never feel stressed out or that my job is overwhelming. If I had to change one thing, I would probably ask from more of a 401K match. Other than that, I really can't think of any suggestions that would make working here better than it already is. If you're considering accepting a position here, I would highly recommend it!
