The company website is either not existing or not activated. May be it is a new company. 2500 QR a month is not a salary that you will be able to save. Free accommodation here in Qatar generally means a bed space with other employees and shared kitchen and washroom. Free transportation in the company vehicle is ok. You must also check yearly paid vacation, return airline ticket from Qatar to your country. You will almost unable to get an NOC for changing your employer if you think that you will be able to change the employer. If you are a qualified person this is not a job for you. Good luck.
