Vantaggi
The work you do directly benefits students attending Utrecht University, helping them in their studies. Evaluating courses and lecturers, by looking at grades and the way students evaluate their discipline of choice, ensuring a consistent and high quality curriculum is something I enjoyed. Also, work life balance is great. Yes, sometimes you need to put in some extra over-hours, but in general working hours are very manageable. You work a lot more if you become project leader on a specific study, but still, working hours are less than at most private firms. Working from home is also no problem. Colleages come from all walks of life, and are (in general) pretty nice. I met some great people I also enjoy seeing outside of working hours. Salary and benefits are also good. You get a big discount on a public transportation fees (NS Jaarabonnement), and can make use of all kinds of University facilities like the Olympos sportfacility, for a minimal fee. It is also possible to attend courses at Utrecht University, for a reduced fee.
Svantaggi
As is common with Dutch Universities, the top-down management structure of Utrecht University can sometimes be slow to respond to a situation, and only after lots of meetings and decision making rounds. This can sometimes be frustrating. If it is clear that a certain situation needs a certain systematic solution, it can be hard to breaking through the system of meetings-and-evaluations to quickly respond. Sometimes, it reminds you of what Jiskefet used to joke about. Although there is room for personal growth, the range of available options for personal development is more limited than at, say, a privately held company. Being a University, there is less pressure to maximize the value of each of its employees than at a private company.
