Hi, if u take this seriously u will be in pathetic situation. Its a general practice here that profession & visa type could be different.
1. If you wish to bring your family, u can never do it with this visa type.
2. You cannot even get Family Visit Visa for any of your family members.

I hope you have signed a contract with the company in which the profession is mentioned & your salary & all agreed upon terms & conditions.
This contract will get stamped in labour dept before your VISA is stamped in your PASSPORT. Make sure that you retain a copy of it.

If your visa is a personal visa of a QATARI who has sponsored your company, i think the law is permitting this kind of employment from 2009. If not you can very well approach labor dept & complain them & pack-off from here.

NOTE: even without finger print, they can cancel you & u can very well go home.
Even after u finish ur finger print & your VISA gets stampped, at any point of time your sponsor can change your VISA type from X to Y. This is permissible.

All the best...
