Pros

Innovative science and diversified portfolio

Cons

Commercial ops, outdated tech, time cards, legal and compliance leave zero room for innovation, fleet is biggest mess I’ve ever seen, lack luster incentive plans and merit increases, no opportunities for remote work so talent is homogenous and limited to east coast

Pros

Decent pay and resume builder if you’re just out of school

Cons

Blaming, toxic culture. Everyone is afraid of making a mistake to avoid being put on some shaming list. Favoritism is how decisions are made. Days are a fire drill trying to work through the crisis of the week while dealing with backlogs, failing metrics, old technology, outdated processes, poor inspection results and deteriorating culture.
