Dear Raja, there are 3 groups in which candidates of ESIC insured quota are categorised into. For the first group, the card holder should have been working either in contract or in service atleast for 5 years as of January 1st, 2019. For the second group it is 4 years and for the third group it is 3 years. After fillung candidates from these 3 groups, if there are any seats left vacant, rest of the eligible candidates will be considered. So you will have to wait until the last round of counselling.
