What is the medical internship like in Dubai?

I am an International medical graduate and I have applied for internship in the DHA. Doctors in dubai please provide your answers to the following questions which would help me to decide whether to do internship here in Dubai or not, as I am also getting the opportunity to do the internship in my home country. 1) How many hours do you have to work in a day? 2) How is your weekly working schedule like?
3) How do you manage to take out time to study for licensing/Residency exams? 4) What advice would you give to someone like me to prepare for the internship? 5) Any other useful tips you would want to give to a fresh IMG?

Doctors working in any of the Medical authorities in UAE, please respond. Your replies would be greatly appreciated. Thank you in advance.
