Run screaming! I lost ten years here!
Pros
They will keep you employed forever, in exchange for staying in 1955 and actively rejecting any tech advances.
Cons
This is an insanely backwards company. For example it was a FIGHT for female employees to not have to wear pantyhose, even with pants. This was in 2014. Women have exactly ZERO opportunity to advance in any managerial level, which I could clearly see even having no interest in it myself. They still have not ditched the waterfall tech pattern; they love to say they are agile but that just means they lie to the business owners as we are not even VAGUELY agile. Every single person I worked with under 40 quit before I did. If you love working with 20 yr old incredibly poorly written spaghetti code, by all means apply! Because they will never change it; for example, they now have a significant dependency on COBOL...and no devs who know COBOL.
