Pros
Ability to wear many hats and take training courses at regarding procurement at client site FDA OAGs. Friendly work environment at client site. Laid back atmosphere. For the most part, the federal employees that you will work with are very friendly and willing to help. A good place to get your security clearance (public trust) which will open one up to employment opportunities.
Kontras
Slow work days. Your used on an as needed basis and there isn't really a consistent workflow that keeps one occupied. I was hired as a procurement assistant, but I haven't purchased anything or aided with government purchases in any way since I have been hired. My current role is to aid CORs with their certification/recertification and to help set up for in-office and hosted training at our facility. I also assist the system support team with workarounds for system errors that help contract specialists (federal employees) purchase goods and services in a timely manner. So really I'm not building any skills that are marketable with other industries. There is a high probability that you will be silo'd into a role that is really not time consuming.
