Pros
Cymer once had an upside. Before the pay cuts, they offered fair salaries. With their reputation, they had to. Cymer is worth considering if you're out of a job and have bills to pay. It might also be worth considering as a first job to pay off your student loans and car loans until a real job comes along. On the bright side, you might learn something about the technology that you can use in your next job.
Cons
Cymer is run by and for the senior scientists. If they do not have the answers, then the problem can not be solved at Cymer. This frustrates both the mid-level managers, engineers and technicians. That fact might be alright if the senior scientists were not insulting in how they treat others. I have never seen a group of brilliant young PhD scientists treated so badly... and that says a lot.
