Pros
MZ time is an unique concept. We move a lightning speed and the projects we take on are enormous. We have big goals: "reach for the stars" aspirations, and we are determined to will them into reality NOW. That kind of vision requires dedication and determination as well as some patience. MZ is the most challenging environment I've ever worked within, it's also the most rewarding. I've grown so much in the last year and a half that I am not only a better employee and manager, but a better person, as well. The amazing feeling of looking back at a year's progress to marvel over visions realized is well worth every OT hour and every frustrating moment it took to do it.
Cons
There's always something that could make things faster, better, easier, cleaner, or less work, but I believe I learned more from the mistakes I've made, from the challenges I overcame and from the roadblocks I smashed than I would have if they weren't present at all. Every company has it's challenges. We work through them and learn from them.
