Hi, Dinesh. Part of the reason that we're being reluctant is that Perl has, unfortunately, an associate perception that Perl programmers aren't very good.

We're unenthusiastic about handing you a set of questions and answers because knowing the answers to elementary questions (what's a hash, how do you use it, how do objects work in Perl) will tell you very little about how good a Perl programmer is.
Put it this way - if you were interviewing for a job, and could tell that the interviewer did not know anything about the subject he was interviewing you on, would you take the job? Would you think that the company was a solid place or risky to get involved with? Would you be leery of whether the company was trying to do things properly in other parts of the organization (like paying taxes, marketing, accounting...)? I know these would all be questions I'd be asking myself.
You really need to find someone in the organization who knows Perl to do a Perl interview. You wouldn't ask the marketing guys to do a detailed interview of a tax specialist - don't try to do that here. You'll either end up hiring a bullshit artist who has memorized a list of questions and answers (like the one you're asking for here!), or someone who isn't very good at Perl but interviews well.
