Hey.

For the SBI Bank Po exan eligibility the minimum and maximum age specified for the candidates are 21 years as minimum and 30 years as maximum as on 1st April 2020. There There is Relaxation provided in the upper age limit in case of the reserved category candidates. Considering that you will not be 21 years old as on 1st April 2020 you seem to not be eligible for SBI Bank PO in the year 2020.

Best of luck
