IMPORTANT: My experience is in the Delivery Department; I know that in Service is very different.
If you are unexperience, you won´t get any trust. You´ll be doing very simple tasks, not for engineers. The learning curve is flat since you won´t have anyone to ask your doubts and the trainings are not offered to you very often, especially if you have other tasks "more urgent for the interest of the company".
Senior people is not very smart either. Except 4 o 5 guys, the rest is not very capable, but they know how to do their job for repetition most of the time. Once something new comes up, they need to call the supervisor, even if they are experienced senior engineers and they are supposed to be able to deal with those setbacks.
On the other hand, expats are not well treated, even when it seems they care about you, if you are not Dutch there are non-written rules within the company, especially regarding the conditions. And there are not close relationships between the employees.
Human Resources has, in short, the worst people I have ever met. They are not honest and they pretend they are there to take care of the employees, having nice words while everything goes as they want, but as soon as you show your drive, your disagreement or you let them know you want to leave the company, you have uncountable troubles. Not taking solely about my own experience, but about most of the people that I see that wanted to leave.
I would recommend a friend to take a job in this company just if he has nothing else.
For ending, it does not matter if in Delivery there are engineer without project and in Service they need people. The competence between departments is very hard (and stupid), without thinking in the best for the company as a whole. They would prefer firing people before admiting they are worse than service and ask them for taking their employees to service tasks. Just nonsense.
