Kindly learn how to use a search engine.

The first two hits EXACTLY answer your question.

What's a closure, and why does everyone go on about them?

Repeat the search for yourself to see what the URLs for these are.

Hang on. First you email the list asking for Perl Interview questions.
Then you email the list asking for answers to these questions.

If you cannot get through the interview based on your OWN PERSONAL
knowledge of Perl, you do not deserve to GET the job. If you are not the
level of programmer they need, do not do THEM the disservice of sneaking
your way into the position. I don't care how much more money you'd be
making. If you can't do it on your own, don't cheat your way in. If you
get the job, I guarantee that as soon as the work gets too hard, we're
going to be inundated with questions and "plz this is urgent" emails, and
I'm going to delete every single one.

People will explain you what it is once you go through the FAQs of this
mailing list.

http://learn.perl.org/beginners-faq

[...]
2.2 - What is this list _not_ for?

* SPAM
* Homework
* Solicitation
* Things that aren't Perl related
* Monkeys
* Monkeys solicitating homework on non-Perl related SPAM.
[...]

[...]
2.9 Other tips before posting to the list

* Check the FAQs first
* Don't send questions asking ``... will this work?''. Try it
first, then report errors and ask the list why it *didn't* work. A good
answer to ``will this work?'', is ``What happened when you tried it?''.
* If your email begins with ``I know this isn't the right place to
ask this, but...'', don't send it to this list :) If you know it doesn't
belong, send it to where it does.
* Check the FAQs first
* Look at the archives,
(http://archive.develooper.com/beginners@perl.org/) to see if your
question has already been answered on the list.
* Have meaningful Subjects. Subject lines like ``Help!'', and
``This isn't working!'' may be skipped by many people, and you may not
get all the great help you want. Try to make your subject lines
meaningful. For example, ``sprintf() trouble'', or ``Confused about
formats''.
