I have been working at Commonwealth of Massachusetts full-time (More than 10 years)
The work is fascinating, and never dull. Constantly changes and evolves. Jobs in this field are in high demand. Currently, the retirement benefits are great, but there is constant assault on this by politicians.
As in most government jobs, upper management changes often. Their experience and attitude toward staff varies widely, often in a negative way. The biggest problem is that decisions are made by senior management in a vacuum, so it is often the case that staff becomes saddled with choices made by senior management that then departs for greener pastures. Frankly, it sux. Moral can and does suffer. Also, salaries tend to be 25%-50% lower than for comparable jobs in the private sector.
I applied online. The process took 3 weeks. I interviewed at Commonwealth of Massachusetts (Boston, MA).
Completed a phone screening, required case study, and in-person interview. The interview was with five staff members. Was asked to present findings from the case study. The interview lasted roughly 30 minutes.
