Pros
Stability, large project, salary paid on time
If you are not ambitious and want only to live go for it
Cons
Management, no policy, no vision, if the manager like you and you were not a threaten you are save and will stay if he feel you are good and you can take his place he will kick you out even if you are super
Managers does no recognize the rule of what is good for the company will be applied, they only apply what is suits them better
