Vantaggi
Very interesting topics to work in and a lot of mobility within projects. They take good care of employees and a lot of vacation time.
Svantaggi
It's stuck on using old tools (like MATLAB) and in old ways. It's not really innovative as advertised, although it works on same old problems on new machines. Most people working there think that they are smart ... but aren't. Also suffers an endemic "not invented here" attitude and reinvents the wheel every other year. Career advancement gets slower over time and ASML encourages people to grow on a managerial role as either: Group Leader (direct line manager), Project Leader (project manager) or Architect (glorified technical manager with limited technical skills that advises other managers with not technical skills). If you are an outstanding Engineer at some point you will have 3 to 4 managers hammering you for results. Encourages a "popularity contest" way of thinking, that means that shallow/easy and widespread solutions are more recognized than solving a deep/difficult problem that not many people understand.
