multiple listings in multiple categories?

Can I have multiple listings across multiple categories - For example, a jobsite that has jobs across a whole range of industries caters for jobs in accountancy - could it potentially be listed in http://dmoz.org/Business/Financial_Services/Employment/Job_Search/ for its accountancy-specific page and at the same time, it caters for jobs in hospitality, so could it also be listed in http://dmoz.org/Business/Hospitality/Employment/ with its Hospitality job search page? The site in question deals in jobs across all sectors, and I am trying to find out what listings it is entitled to - I know from another thread that you are allowed a regional and an industry listing, but this area seemed a little grey to me... Thanks in advance for your help,
cheers,
steve

What you're asking here is if it is OK to submit deeplinks. Listing deeplinks is the exception, not the rule. Without your URL it's difficult to say, but from what you're writing here there's a 99% chance that the answer is 'No'.

Most probably you should only submit your site to the most appropriate subcategory of http://dmoz.org/Business/Employment/ .
