Slightly OT, but I've been interviewing long distance recently, and I used the following 3 questions tasks (ffs). Bear in mind these are for web application development, so front end is important too.
- create a calculator using HTML/Javascript, that processes the entered equation through a Perl CGI script and displays the result. This tests JS usage and, the biggie, whether they untaint user input in the CGI before 'eval'ing. Also, use of CGI/Mason/Template Toolkit is examined (and mentioned in the original question).
- Compare two arrays and show the elements that exist in both (I actually screwed up in my live question, but the answers were still informative). This is a great question because it shows how someone thinks. Lower level devs use nested loops (I did, when this was thrown at me a few years ago). Smart people use hash slices. Really smart people use 'undef'd hash slices to save memory (or, rather, time - ty runrig).
- Search google for a particular search term and present the first ten results in a web page. Another good one to see how someone thinks. LWP is quick and dirty, the Google SOAP Perl API is elegant, yet non-intuitive if you haven't heard of it.
Maybe we should start a quiz section where these sorts of questions can be dumped? I'm sure there are many more that push you to think laterally - or use aspects of Perl that involve some interesting thinking.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
