Mine has been working in Kuwait for 8 yrs. Arrived my house 4 months. So far quite good. Good in taking care of kids, household chore ok, cooking learning v fast now ok, cleaning marginal pass. A bit slow but acceptable. Not v smart in handling special tasks as her mom was full time and give her all instructions in details.
When interview, need to make sure she is capable on your desired tasks cause they usually have several maids in a house. Put your requests such as no phone, no computer, what holiday, etc, during interview. They are not easy to get a job before coming to HK and usually more acceptive to our requests.
