Pros
They have excellent brand recognition. I actually worked for Macromedia and when we were acquired I was initially excited but then decided that I wanted the small company feel back in my life. I am still in touch with a lot of people who went to work at adobe and they like it. One of the main reasons I would have stayed longer was to stay working with the people that I loved to work with. The best part about working for Macromemdia was the outstanding people I had the pleasure of working with each day. I miss that place.
Cons
The company was too big. Being acquired was a major challenge for me personally. Macromedia felt like a family and Adobe felt more like a small part of this big place and I was not sure how I fit in. I never really felt integrated into the Adobe family and I was not sure if my opinion was valued. I questioned whether or not I could make a long term impact. I was also concerned that I would have to start working more and more from the main HQ office in San Jose, which is really far from where I live.
