Working for HMG

Hi
I am going to start working for HMG as consultant in medicine. Can some body working there tell me how is the on call there as I am asked to do one in three on calls which I find very demanding. What would be expected from evening shifts, is it mostly clinics? Would there be any straight shifts?

Hi did you move to saudi and start working for HMG? as ive just accepted a post and would like to know more about the job.
