It will not take another year. If they publish pre selected candidate list in this month or in september then there are chances that the interview program will start in october session or most probably in november. And i think pre selected list is almost complete that is why FPSC sent letters to others candidates down the merit line during month of july, may be FPSC became short of experienced candidates. Now work for these candidates is underway. All formalties lies with pre selected list after that there is only interview.
