Brother,

The offer you are getting, benefit wise is the best in Qatar, I can't say if the salary is according to what a engineer may get, but the housing and other benefits, what you will get, you will be satisfied. These days a normal 2 BR furnished apartment in Doha costs 5000 p/m and family expenses doest go beyond 1500 p/m.

So, that means you are completely saving your basic, half of the housing in your pocket, about a lakh rupees.

As far as transportation is concerned, there will be no problem in financing a new car, company may also lend you interest free loan to buy a car. A normal toyota saloon car costs 60000 riyals.

In case you need more information, do let me know, i will be happy to help you anytime.

Do negotiate with the company on the salary part.

Regards
envoy.
