Pros

Pay is alright, benefits are good, great work/life balance. Stability with Berkshire ownership. It can be a stable place to learn a few skills, but you will exhaust the learning potential in about 9 months.

Cons

You will not grow. No talent pipeline program. HR and management seem oblivious to this. I saw great people come and go quickly as they realized this. I've been gone for a year. It is run with zero vision. The strategy is to not have a strategy... just keep things the same and try and generate a few bucks. Grow the business or change the processes... nope. While there may be a couple good Directors and up to learn from, there are far more who are just milking a paycheck and afraid to present ideas to senior management.

Pros

Great history and tradition. Perceived safety of Berkshire Hathaway family. Opportunities for bringing JM into the 21st century with many of its business practices.

Cons

Very conservative both politically and organizationally. New ideas need to be socialized thoroughly before they are accepted. While there's a benefit to being part of the Berkshire Hathaway family, there are financial expectations that need to be met.
