Avantages
A lot of stability, they do want you to stay there forever. The people surrounding you have been there either a few years or 40 which means there is a ton of expertise. Everyone is generally very kind and polite. The resources and facilities are huge, as well as their knowledge base. The best part is the flexible hours. 40 hours in a week and basically whenever you want. It would be hard to revert back to working on Fridays now.
Inconvénients
It is strange when they announce we achieved billions in profits but we only got 95% of our bonus because some department didn't meet their deliverables, even though the rest of us did. When we asked what was our incentive then to work harder they told us it was an honor and privilege to be an engineer and we should have an intrinsic satisfaction in just doing a good job. Also the bureaucracy of the company is staggering, it is difficult to complete almost any task without jumping through hoops.
