Pros
ASML are about some of the best corporate overlords to have. It's a highly matrixed organization that separates business and technical management into different tracks, which ensures high quality decision-making. Work-life balance is highly valued and respected, if unevenly achieved. The people I work with are some of the most talented in the world, but the hiring practices are not clubby or exclusive like FAANG. There is a great culture of openness and debate; you will not be punished for speaking your conscience. Even at its least sexy, the work is still amazing and mind-blowingly advanced. ASML is a high-pressure environment, but most of us don't actually mind the pressure - former ASMLers most resemble military veterans' level of performance under pressure and high drive relative to other companies.
Cons
Unfortunately, the company is choking on its own processes; we are not nimble enough to get simple engineering changes done in a remotely reasonable time. US HR is parasitic and speaks out of both sides of its mouth. Relentless customer focus driven by paranoia about our dominant market position has turned into a management culture that rewards obsessing about escalations and kissing daily [rear-end] at the expense of actually doing your job or planning ahead to prevent future headaches. Too often, the people who can write a pretty slide deck while blaming others for screw-ups are promoted over those who are competent and selfless - it's about 50/50. The only way anyone moves up around here is by leaving and then coming back at a higher level.
