MoH interview and license process for doctors

Hello, can anyone enlighten me on this please? I have been offered a job in Kuwait and need to get my medical license done. I was told that it involves an interview - I hold a CCT from the UK and  x FRCS with over 20 years' experience as a doctor.
The MoH website seems to be unhelpful as it either leads to a blank page or freezes.
How is this via/interview held, and who is it by? Do they cover your sub-speciality only or eternal topics as well? I'm obviously worries about being asking about topics I have not encountered for over 20 years!
I'd really appreciate your help - thank you.
