Dear Alex,
It all depends on your expectations and on your current situation as well as your resume.
If you think this is what you're worth then just take it till you get a better chance.
My personal opinion, this offer is too low, you will not be able to survive one week with this salary.
With such a salary you will not have any social life, won't be able to ask a girl out for dinner or even ask her to the movie theatre coz it's Qr.30/ticket!!!!
My advice to you is reconsider and don't rush, life is full of chances, sometimes you just have to skip one chance to get to the next one which could be better (or could be not)!!!!
But like i said it all depends on your expectations.
Good luck to you and may God help you make the best decision.
