Anu,
Just be aware that there are many jobs advertised but in most cases you could end up getting highly skilled jobs with very low salaries - R4000 monthly.. Approximately $750 per month .
With that you cannot even pay for your accommodation and utilities.

You should look at a listing of ITC companies in SA, on the internet then go to their web sites apply on there.
Most companies now have their own web sites where they advertise available positions. You will get better salaries on there too.
That is true for most jobs in SA.
