Maggie–be persistent, but realize that the game is rigged. It’s not about how much experience you have, it’s whether or not you know how to play the game. And by that I mean, do you know how to “beat” the KSAs and maximize your points? That is what will get you the interview, and ultimately, the job. I don’t want to give too many pointers here in the message boards, but let’s just say there’s a science to USAjobs. Sometimes you just can’t win because there are a lot of shenanigans going on behind the scenes. Oftentimes these hiring managers will close job postings if they don’t get their desired candidates. My suggestion is continue looking elsewhere outside of government, and when you do apply for fed jobs, put in only for jobs you really want. Don’t waste too much of your time on this nonsense.
