To me it appears that you have to take a lead. Contact any advocate at Hyderabad, that is sincere , file writ mandamus for directions to ZP for providing a post suitable to your qualification. If they have in writing asked you to report a subordinate staff include this.
What you want is remedy, and as the existing regulations help you, as there are thousands of posts being notified very shortly, act as immediately as possible. A reasonabe advocate may charge minimum of Rs.10,000/- to Rs.25,000/-. But he should be sincere.
