I know this is really a big question and a long criteria.
But i know here i am able to remove my problem.
I have to give interview for Portfolio Management, Mutual Funds, Fixed Income.....
But i really dont know about all these things, mean i dont know functionality of Website for above terms used.
My idea is that if i have some example or any functional document then i am sure , i can explain every thing.
maybe the best thing would be for you to speak up and admit you aren't the person that should be performing the interview?
Not trying to sound harsh, but there are two things that I think are unforgivable with interviewing:
1) the interviewee taking up the time of the company knowing they aren't qualified for the position and trying to B.S. their way into a job they can't do
2) going to an interview and having my time wasted by a person interviewing me is no where near qualified or knowledgeable enough to adequately gauge my answers and to whether they are correct or in line with their needs.
