Jay, I would feel that PL/SQL tuning is the same as SQL tuning. Just pull out one of your complicated Explain Plan or TKProf outputs and ask the Interviewee (is there such a word?) to explain the meaning. Also quiz him/her about the various joins and the approach he/she would take when a DBA/User complains of a slow query - If 'trace file', 'tkprof' and 'explain plan' don't appear in the answer, then you may as well stop the interview :)
