Thia may actually take 2 hrs of a good discussion. I'd personally hire this guy if he answered 80% of these questions!

Describe the various components that make up a database. Then, go into detail describing the various components that make up an instance. How do these components interact and work together?
Anyone who can do a good job describing the databases (datafiles, redo, controlfiles) and the instance (various background processes and what they do, SGA, how it's divided up, etc) is going to have a pretty good knowledge of Oracle.
If candidate survives that one, favorite questions seem to be:
Describe a recent database corruption issue and how you recovered from = it.
What's a nested loop join? Sort-merge join? Hash join? semi-join? anti-join? Self-join? outer join?
Describe scenarios where it may or may not be appropriate to use a B*Tree or bitmap index.
Describe your approach to tuning SQL. What tools do you use? How do you approach the problem? How can you measure the improvement that's been achieved?
A user complains that the system is slow. What do you do? Where do you begin?
There's some questions that ought to keep him busy for a while...;-)
Good luck,
-Mark
