I would spend some time working out some sample XML/XSLT problems.  It's almost impossible to guess what questions they will ask.  Though, in many interviews over the last few years (I do project consulting, so I've had my fair share of interviews), I have yet to meet an interviewer that actually asked me anything about it.  I think it's because most of them don't know about it anyway.  I often will try to guide the discussion to XML/XSLT based solutions, mostly to find out what level of exertise there is among my future associates.  

I have a lot of XML XSLT examples on my web site you might find interesting.  If you have IE 6, you can run most of them right from the web page:

I'd start out with some basic questions, like given a set of nodes, how would you create an HTML table.

http://rdcpro.com/Members/rdcpro/snippets/simplegrouping/

If you used a for-each, I'd modify the question to get you to use an apply-templates.

If you can take some real-world XML, and create a well formed HTML table out of it, you'll probably have a basic knowledge.  There are many techniques that are more advanced.   Another good question would be to take the table you started with, and then add a TD cell that contains the sum of a set of nodes.  

Next, I might get you to add a recursive routine using call-templates.

Grouping is always a difficult issue, so I'd probably press you to come up with a relatively simple XPath grouping solution for the table:

Then I would probably take the table example a bit further, and see if you knew anything about Muenchian grouping, by asking you to group the data in the table by some value.  

http://rdcpro.com/Members/rdcpro/snippets/columnrowgrouping/
http://rdcpro.com/Members/rdcpro/snippets/groupinggrades/

And if you want to know how this Muenchian grouping thing goes, I have a short tutorial on it:

http://rdcpro.com/zones/xml/xslt/faqroot/faq-grouping-1.1 

But first figure out how to create a basic HTML page with an HTML table on it using XML/XSLT.  

Other good questions would revolve around how you deal with namespaces in XSLT:

http://rdcpro.com/Members/rdcpro/snippets/xsltandnamespaces/

But really, even if they're experts there, there are so many questions to ask, you'll probably only get at the most one or two on XSLT, unless that's what they're hiring you for--in which case you should be an expert.

Good luck!

Mike Sharp
