My father worked at a government bank, but he’s been missing for 20 years now. We filed a police report, but there’s been no trace. As his son, can I apply for his job at the same bank?

Indian law doesn’t have a provision for inheriting a government job. Even though your father was a government employee, you cannot apply for his position based solely on your familial relationship. You would have to apply like any other candidate and meet the bank’s eligibility criteria.
