For first timer the offer is a bit good., but you have to negotiate more for accommodation at least min 2000, you will get a little bit decent room.

Draft Expenses:

Accom: 1000 - Sharing room/partitioned room in a family ..etc...
Comm/Internet: 200 - Min per/mos it depends how you utilized it
Food: 500 - Min / depends your lifestyle
Trans: 500 - Min / depends on the distance and the schedule of work, if it is double shift in a day it will be more

Remaining will be budget for your shopping spree and savings depends on your lifestyle.

The offer is not bad BUT if you can negotiate more its better.

Good luck. kita-kits sa doha.
