Growing... Means lots of work. Better than a lack of work.
Pros
You will fall in love with the people you are working with. It'll make it very hard to leave if you would even consider it. The owners like to have fun, and employee happiness is definitely one of their top priorities. They will pay you what you are worth and compensate health cost a lot! They also make you feel like your ideas and concerns are of true value to them (a Pro and Con). Everyone here is always very helpful, and really into sharing knowledge. Hard work is recognized and rewarded both publicly and privately. They'll make you feel good about your hard work.
Cons
The company is in the middle of some growing pains (a Pro and Con). With growth comes change, and change is often a difficult thing to embrace. Mistakes are made and then corrected. It's definitely a trail by fire sort of thing, but I believe they will make it through. You will work hard. Remember they are growing (which is good but hard). That means fast pace not slow pace (a good and tough thing).
