Pros
The machines we build are truly stuff of science fiction. And being the only feasible provider of EUV-based photo-lithography in the world doesn't hurt either. If you're bright, driven, and don't mind the super-fast pace - then you can have a bright future, with good benefits. HR is overall very good - lots of employee events, and community outreach as well
Cons
Too many projects, not enough time, and a mistaken belief that more employees lead to faster development. This combined with extremely aggressive program managers leads to over-worked and stressed engineers. Another issue is the inefficiencies of working here - tons of meetings, emails, leaving one with not enough time to get actual work done. What's more, this is a very process-heavy organization. While there are improvements being made to automate some of these, it will be a long time before working here becomes less than a painful exercise. Finally, there are far too many ASML-specific guidelines for software development (from coding standards, language use, architecture), which lead to a long learning curve, and many non-transferable skills.
