Pros
Good salary, 40 vacations days, very good pension plan and insurance, flexible work hours (including working from home), good work/life balance mentality, 14-20 % profit sharing, stock share program, semi-annual automatic (small) pay raises by the 'CAO', bicycle plan, very smart and friendly colleagues, enthousiastic drive for the customer and technology, possibility to travel to customers worldwide, possibility for horizontal movement (different roles/sectors) and vertical growth (leadership/management), very professional company with great care for its employees (ethics and cultures). IMHO, ASML is one of the strongest and best employers in NL, especially in the technical sector. I'm a long-time ASML fixed employee and I will probably not leave until retirement!
Kontras
Large company, so there's some unavoidable beaurocracy and many management layers. Rather rigid salary scales, so you really need to prove yourself to raise in them. Work can often be quite hectic and a flexible (agile) mindset is recommended.
