Pros
I'm a long-time former employee, and had I not decided to pursue my passions outside the software industry I would very likely be back at MetaCommunications. I've seen how a lot of companies function, and have owned/operated my own business as well. And from that perspective I can say MetaCommunications is a great place to work. Sure...they had some growing pains in the early years, but what company doesn't?
Cons
I don't really have any Cons...but maybe a word of advice. If you have the drive and desire, and want the opportunity to become the best at what you do - whether it's programming, support, professional services, sales, marketing, or whatever - then MetaCommunications is a fantastic environment. If you want to become a true professional in your career, MetaCommunications is the place for you. If you are simply looking for a "job" where you come to work, put your time in, and nothing further with no real true ambitions or desires, then MetaCommunications may not be for you. And I say that for both your and the company's benefit. Seriously - look inside yourself, do some soul searching, and ask yourself what it is you really want to achieve in your professional career - if you have the inner passion, drive, and desire, then MetaCommunications will help you achieve it.
