Pros
Great technology, lots of expertise among colleagues. Room to share your own ideas. In general a respectful communication. I always felt like I could speak my heart.
Kontras
Projects are slow and can be stopped suddenly, without proper explanation from management. As a lead mechanical engineer, I worked for 4 years on a project in which the design work was only a few months. The rest was endless risk analyses, small design iterations, documentation etc. I understand the products need to be perfect, as down time is extremely expensive, but it really takes the fun out of the work if things take too long. Especially when the project gets cancelled when it's practically finished. This was the last drop that made me quit my job. Roles are organized around a module that needs to be finished. Every mechanical engineer needs to do the same job, for a different part of the machine. Instead I think it would be better if people were used for their talent more. I felt like my creativity was being wasted, by having to spend my time on bureaucratic processes, while other designs could've benefitted from my creativity. People work too isolated and I struggled to break loose from my chores to be able to help others. ASML seems to think quality is mainly created by following processes. I strongly disagree. I think a lot of the design reviews are not good at finding mistakes. People need to be more involved in each others projects, so real peer reviews are constantly taking place.
