This is a good employer if you are planning to grow yourself in corporate business field, and increase your knowledge in most of technical solutions field.
Every day you need to plan your work and the best case if you do it by yourself and can work without any "order" from your management, this will be a good approach, if not - prepare for a "hard FtF talk" later. I've learned a lot of stuff in a business processes, corporate culture, technical knowledge and know-hows from my colleagues. If you are participating in a project business, like me, it's a good way to be involved in multi-national projects and understand all pros and cons of this business during project lifecycle and increase your skills.
The hardest part of the job is face with a difficulties which stops yourself to implement what you need to do, such as a business processes, technological solutions, relationships, managemet.
still feel yourself in a "soviet working system" - don't expect that management will spot you, and if you are not someone's good old friend from his/her off-company life.
"Safe Haven" if you do not aspire to a better - and will simmer....
Management; if you are not German - do not expect too much
