Age limit for a public sector job in India / Telangana state - 54 years for handicapped, and 49 / 45 for rest

Wish this is not true, but seems 54 years is the maximum age a person can get in to a job. I am not sure but the state of affairs is worrying me. Taking the retiring age of 60, they have a maximum service duration of 6 years? Then another recruiting exercise to happen? or extend the retirement age then going to pass the job to their children? Who is going to bear the costs??
