Pros
Generally, you will surrounded by nice, caring, dedicated people. The US branch of the company, formerly Square D, is a stable old-fashioned organization pretty much straight out of 1950s America. It's one of the few places that still has a decent retirement program, provided you put in your 20+ years of service. The company took some hard knocks a few years ago, but seems better positioned now to respond to market conditions.
Cons
The company is too focused on internal initiatives at the expense of innovation. And a lot of these initiatives are pie-in-the-sky, implemented from the top down, and fail to deliver on promises of streamlined effort and cost. The ratio of managers and support staff to core development people is too high. You're considered lucky if you get to do actual development work rather than reworking old or brand label products.
