Is it true that if a candidate from a reserved category (OBC/SC/ST) gets a job after availing reservation benefits in a competitive exam, they can’t apply for an open category position? I’d love to understand this rule in detail. Can you help me with the information?

There is no such rule in Indian law preventing reserved category candidates from applying for open category positions after availing reservation benefits. A candidate can apply for any position they are eligible for, regardless of their previous reservation status. However, they cannot claim reservation benefits again in a subsequent attempt for the same position.
