Thanks everyone. I understand what you are saying but what is the best way to ensure I clarify all these things beforehand. Consultant did not clear this doubt of mine.
I also asked about the PF, gratuity and annual bonus but I didnt get any answer for that as well. He said it is standard & you will get to know only when you arrive at Doha. Appointment letter will be given upon arrival. I will be on probation for 3 months and only after that I can bring my family there.

Is this the regular/standard process for the employment in HMC? How best I can safeguard my family's interest?

Please suggest.
