Usually if they want you, they would give a verbal offer in the next 2 days before they start their long internal clearance process.

Anyway, since HR already told you 1-2weeks should probably wait and see at the end of next week. I’m now in a similar position as you, interviewed last week and was told by the panel to wait 1-2 weeks. I don’t have a good feeling cause in my previous govt positions, those that offered me always called the next day. And if its a rejection, its 2weeks after interview.

Maybe they changed the way they work? Hopefully both of us gets the job!!
