Joined as a dx9 but honestly not enjoying it. Can veterans answer some questions I have and provide guidance pls?

- currently it is quite draining compared to previous job because no one actually talks to me. I think the uniformed personnels who are bosses just don't care about the existence of dxos. Secondary citizen vibes.

-can someone share how long promotion usually takes for dx10,11 and so on? Since it is a time based scheme after all.

I am under the impression that dxos are paid higher than other ministries but not sure if it is factual.
I do enjoy the work and can deal with the distance and red tape, but it just feels like I'm a temp worker and there's no future here. Help?
