Pros
Hands down, the best reason to work for Boeing is that they have paid (in full) my tuition costs while I've been interning. I worked part time during the school year, and full time during the summers, and everything has been taken care of. Also, if you take an educational leave of absence (i.e. if you can only work in the summers) they will pay for that year of school in between your summers. Also, the products that Boeing manufactures gives you a reason to come to work everyday. We provide support to our troops overseas everyday, and that makes me proud.
Cons
1) The aerospace industry has a "good ol' boy" atmosphere, in which young people and women are not looked upon in a positive light. 2) They promote new ideas and fresh outlooks, but every new suggestion gets shot down. 3) Systems are out of date and often malfunction; while the company is moving towards a "common process," the transition period just makes everything worse. 4) Some systems are too common, i.e. when I had a question about payroll, I was directed to the company operator and was told to submit a ticket... there is no specialized help and therefore no quick solutions to any issue. 5) There is hardly any opportunity for upward mobility. Even to be considered for promotions, an employee has to apply for that position. Also, management is detached and seems to only be in their positions because they've been there the longest. And no one ever leaves, so there are rarely any open management positions. Rotational programs for college hires seem to be well recieved, but are only open to 3 individuals per year - so most of the work force is 30+.
