1. Most probably previous and new both qualifiers for interview will be considered. (they have enuff problems ab unko court jane ka koi shok nahi)
2. It is not necessary that FPSC will call 3 candidates for 1 post. This range normally goes from 3 to 5.
3. I dont know which interview you are talking about (personal hearing wala ya final selection wala, final interview wale most likely questions to main ne bata diye, about personal hearing interview see i have posted somewhere, i think in this thread).
4. Well this relies heavily on your interview performance. (if you are PhD in criminal psychology then they may consider this qualification , otherwise very little consideration is paid to academic record. written test main 19 20 ka hi fark hota hay, so no consideration).
5. I dont know how I can answer that (Kabi FPSC ka member bana to shayad bata don .
