am from KAMC, well as any new comer, the anxiety of going to a place far from the philippines is understandable. google the hospital for its facilities and what not. with regards to getting along with nurses and doctors- my dear, the feeling is the same when you come to a new work place: some oldies will make your first 3 months toxic; some will welcome you like an old friend; but this will also depend on how you are going to act and relate with them. of course they will be checking your performance, and once you hurdle that 3 months then you will be ok. the doctors- the same.
there may be discriminations that you may feel at work but we filipinos are strong and intelligent and with the help of the Lord, we can overcome all of these.
the only difference is the culture, in which you really have to adjust- the language, the weather,their way of dressing and treatment of females etc.. just read on saudi culture.
if you are coming here, good luck. take this chance as a new and challenging experience and always have the right and bright attitude, then you will go a long way. : )
