Dear Moez,
Also, to mention, it depends upon sector you are going to work with. For eg, if you'll go for sector such as Food & Beverages, Food Retail etc, wherein under FDA Act, all the employees dealing with need to compulsorily undergo pre- Employement Health Check up as well as require Food Handler Certificate from Medical Practioner.
However, as Priya mentioned earlier, that the same practice has been adapted internally & depends upon the job requirement.
Thanks
