It's an ancient, huge, French-Swiss company. You can start working there, you can end your career there and nothing much will happen between the two. You'll never matter, you'll work on problems but nothing that makes a difference, you'll never be credited with anything, you'll never earn any real amount of money, and whether the page numbers in your design doc are correctly formatted will have double the career impact that the design itself has ... The only thing that matters to anyone at the company is how many years you've worked there or if you've invested large amounts of money in the company.
If you want your entire career to be exactly like, let's say, the first year of your master study at university, with exactly defined problems to be solved, then get a thank you, maybe a nice compliment if you've done exceptionally well, then to see your solution disappear and never even be used anywhere (and certainly not voluntarily by a customer) or if your family has enough money to build a house out of 100 dollar bill bricks, it's the perfect place. A place where people use extreme social pressure, even crimes, to get the slightest of advances within the company, because there is no future there. I would make damn sure all my interests lie outside of work though, even in that case.
