Cons

Some places are straight production shops and there will be limited opportunities to grow in them. When you make a mistake it can be huge and cost 10s of thousands of dollars to fix so you are often on edge.

Pros

Constant Challenge making each day unique and fun. Not hard physical labor but mentally challenging. Constantly evolving skillset in an industry that is always changing and growing.
