The seniority of candidates appointed in BPS-17 in any government department (Excluding PMS/ETO positions) upon the recommendations of KP Public Service Commission is determined on the basis of the overall merit score in the recruitment process or on the basis of who ever joins first? Are The Civil Servants (Seniority) Rules, 1993 applicable on the employees recommended through KP PSC as well?

Dear fellows please guide me about seniority status rules in federal govt as I am a bps 17 officer in federal govt dept.
It is better to elaborate my issue before asking question. I appeared in FPSC exam under advertisement No F.4.95/2008-R on 14 Oct 2008 and written portion result was announced on 27th Jan 2009.
I passed written portion and called for interview however I passed but my name was put on waiting list .one of the candidates (Punjab Domicile) decided not to join and I was given a chance/offer(Feb 17 2011) which I accepted happily .As I am Punjab domiciled and I joined on 2 March 2011 . My colleagues who passed under same advertisement joined early in order of merit and quota 2010 .
Now I am last to join according to the situation I described above . Now in seniority list my name is not with my group instead my name is set according to the date of joining (2-3-2011) .before my joining office 3 officers from bps 16 were promoted to 17 in January 2011. However whatever the circumstances my right of seniority with my group is disregarded Now what should I do.

All seniors are requested to comment>
