Each of these offer the ability to browse for skills/degrees.
For example, I just did a search for "graduate jobs australia" in Google and followed the top link to "www.seek.com.au/graduate-jobs/" where I was able to type in "engineering" and "bachelor of engineering" and saw a refined list of applicable opportunities.
In that above list, I'm presented with jobs that I would not have considered because the search was not job title based but degree based.
How do you differ from that experience?
I like the UI experience. You'll definitely need to consider a "location" field because Australia is a pretty big country!
Keep up the good work :)
