How do you get governent jobs?

I'm looking for work in Louisville, KY and would love to find a government job (post office, court house) but I'm not sure how getting a governtment job works.

apply when they advertise or look up jobs offers on their website.

u have to apply online .. . .
There are companies who help fill out the paperwork and resumes to help get certain jobs. You have to have the right number of key words often to get enough points to get the jobs. Also you can find them online I cannot remember the exact internet address of the site the VA Phlebotomist told me about but it is a government site.
1. Bang your head with a ball pin hammer
2. Talk in single syllable words
3. Sniff glue once in a while

Now you are qualified
alot post on internet, or in news papers,, some require a small fee down and some require and entrance exam ,,, if you want the true government job,, join one of the armed forces (i recommend the Navy),, i was in it and it gives you the best careerchoices and the ability of flexability
good luck, hope you dont mind cold in chicago,, like -10 to -20 w/out the wind chill,, if you get winter boot camp!!!
Are you lazy and incompetent?

Those seem to be a requirements.
