Work is easy here as the expectation is low. If you can cope with the inefficient and ineffective working envirnoment, the working life is very easy here.
Envirnoment:
Safety is a problem here but it won't be an issue if precaution measures had been taken. It will become part of the life like people staying in some area of JB and KL which robbery happens almost everyday.
Food and grocery here are expensive. It won't be an issue if your company will provide the food and daily supplies.
If the offer is good, it is worthwhile to spend few years in this country as you should be able to save a quite substantial amount of money.
