Pros

Knowledgeable and hard working study start up specialists

Lack of structural and change management support in the project management organisation resulting in low knowledge from the country startup specialists and supervisors to support the reporting into the Start up system.

Pros

I’m comfortable here — which frankly, is wonderful. Based on my specific role (which is a bit unique) I have great work/life balance and great pay. But requires setting boundaries and being firm.

Cons

It’s an agency, so it can be stressful and demanding at times. Upward mobility depends primarily on willingness to do new business.
