@rilwane, physical check up which could include blood tests(to know ur bloodgroup,genotype per-adventure any accident occurs; they'l know exactly how to treat you; not forgetting, to find out if you have any disease or ailment that may be harmful to others in the organization), urine and faeces test, eye check-up(to find out how bad or good ur eyesight is). Most times you are not expected to eat before your medical examination and it is supposedly the last stage before u get the offer/employment letter. Hope this helps.
