Call was an introduction to GSA phone call and to explore personal capabilities. Turns out it's another recruiter gate keeping based on personal subjective opinions. Got email that I was denied to move forward when the meeting wasn't an interview and there was no reason explanation provided. When I asked for clarification was ghosted.

I applied online through the typical government process. There is a survey to file out as well as several forms. This is a prerequisite to an in person interview. It is not difficult but be prepared to answer potentially long narrative questions and pay attention to using words associated with specific skills or knowledge required for the position.
