Pluspunten
Lots of projects to work on, nice co-workers. If you are lucky with a technically competent supervisor, you will thrive. But planning for the long-term is difficult -- there are organizational changes (restructurizations) that happen more often than 6 months! Meaning that your position is in flux most of the time.
Minpunten
management is non-engineering, often incompetent, but arrogant and brutal to defend their salary at your cost. Projects are not assigned based on technical skill but through internal process of managerial decision making. Since most managers are not technically skilled, projects are assigned and evaluated based on a political and other non-technical reasons. This creates very poor and subjective evaluation process.
