Question: What is your job?

[storm]

Normally you can ask "What do you do?"

So are these sentences below equivalent to "What do you do?"
1. What is your job?
2. What is your occupation?
3. What is your work?
4. What do you work? (Is this grammatically wrong maybe?)

And how do you use
1. My job is .............
2. My work is ...........

You know I love learning the right things

Thanks a lot
