So what do most people here do for work?

Like...well...everything...

I kind of got the impression that most of the expats were in some way connected with the oil company, and I was curious whether that was accurate or not. 

(If I came, I wouldn't be, so I was wondering if that would be unusual).

Oh you can find every single profession here, like im a game developer my self.

Construction field is well spread here too. There are also various IT companies that develop sites/apps.

Actually i see that most expats here are teachers

Also most fitness instructors are westeners...

Oh well you won't find bartenders ( as alcohol is illegal) and prostitutes ( if the latter is considered as a profession XD)

That's really interesting, thanks.  It's so hard to know, when you're reading about a place, how much is reality and how much is someone else's projection!

oh yeah that's totally true!
