Avantages
If you like the corporate "dance" and like to be promoted through the ranks without having the relevant skillset, then yes, Steelcase is your company. Works only if you are a man though. You will encounter great people at times, and it will give you hope that what this company promotes as core values is not only a marketing gag, but in the end its just another corporate that doesn't walk the talk. If you are into that kind of game, go for it. They are leading the market, they have great products and there is a lot to learn.
Inconvénients
If you have talent, if you are innovative, hungry and if you want to make a difference, take your energy elsewhere. There is no room for growth, on the contrary. Its a total boy's club and the gender pay-gap is enormous.
