On multiple occasions, FCPS has admitted to leaving positions posted well after they've been filled. After submitting an application and waiting for a few weeks, I'd get a form rejection saying that they had hired a candidate before receiving my application.
Given that it's an automated application system and my application was received within seconds after I hit submit, the layers of incompetence from HR are unbelievable. Not only did they fail to update their own job board for several weeks, but they went so far as to spell out their own unprofessionalism in writing.
EDIT: As stated above, this was my experience on multiple applications with FCPS. GlassDoor originally removed this review because apparently "multiple positions" don't exist within FCPS. Glad to see they agree, ha!
