So you're just referring to government IT recruiting? That's certainly nowhere near what happens at any of the companies I've worked at. There is usually some placement firm, I would say located in the US, that's supposed to filter out the list of candidates. Then there is a round of phone interviews. If they make it past that they there are in-person interviews. The interviewers then meet to come up with a final yes/no whether the person will be offered a job. That's at least the high level. People from HR could do some of the initial interviews before having the hiring manager and people from his/her team conduct more in-depth interviews.
