I'm holding a 4200gp post in a PSU at time, I want to apply for State PSC, I intimated my department for the same but they sent the application back asking to mark the post i want to apply for, they told it have 2800,3600,4200,5400 all gp jobs, and on the same gp or below i'm not allow to apply as per govt rule, I have a doubt as this rule applies to UPSC, SSC or state psc as well..What are the rule for applying SSC, UPSC, state PSC... kindle focus on this rule also give a source to tell them.
