dear feet,
exchange rate as of today is 16.9 indian rupees for 1 qatari riyal. 19000QR is fair for a medium level employement. since you are offered with housing and other perks, all together you may get an amount equal to 30,000 monthly(i guess). times 16.9= 507,000 indian rupees. is it a fair amount in your current situation..?? now, you may reduce the expenses including housing etc. doha rent is always unfair. for a two bedroom flat, you have to pay 6500 QR at least. then grocery, transportation(car loan) etc...thus, at the end of month, you may have your 19000 in your hand. times 16.9 = 321,000. is it OK for you..?? then accept this offer. more over, once you get an opening abroad, the door is open for you to learn about you and your salary. all the best.
