Doctors in Qatar (help please)

Hello
I am an algerian medical student
I wonder how can an algerian doctor work  in Qatar
What does it require?
Do algerian doctors need to study some more years there before working ?
How is dorctors' life in Qatar?
Are algerian doctors at the same level as other doctors in Qatar?
Please help with any information that can be useful
Thanks a million
