Exams to get a job here in Medical field?

Dear Friends,
Need your advice and suggestions please...
I have done my Bachelors in Microbiology and Food and Nutritionist university course.
I am sesrching for a job here but came to know that i need to give some exams in Qatar to get a job here.
Can anyone please advice about it.
Serious answers please.
It will be difficult for you to get an employment in medical/healthcare field without work experience. Try to start your career in your country first then find an employment here later on.
