Pros
Pay can be good, you have very smart people to work with and most are pretty passionate about the job. Benefits are good and bonuses are regular, health plans have good options. There is an encouragement to keep learning although the monetary support has gotten smaller over the years.
Cons
Although pay can be good the system that determines it is very subjective and you often get shafted. Also I see all the time that Boeing values diversity but my personal experience is that they didn't really care. There is very little diversity in upper management and it feel like everyone is solely focused on metrics and not the people or the product. Working for a giant corporate machine gets old especially when it's one with as much baggage as Boeing. Boeing is the antithesis of nimble right now and very stuck in it's ways.
