Kabayan dont compare yourself to other of your friends working here in qatar it depends upon the the company and experience abroad, if this your first time its fairly enough what they been offer to you. I started working before as a document controller too with a salary package of 2,500 QR only free transportation still i can save and send money to my family it depends with your lifestyle how to save your money but now with the experience that i have im working now in a good company with almost 5 times of my salary before for me its a good start and your lucky enough to have an offer like that.still 99% is for you to decide if you will grab it? were just telling you the reality.Goodluck
