Well writen stuff. I'll be interviewing a guy tomorrow and I learned something new from your stuff.

Now, one point was never mentioned above. You want to know if the person knows Oracle well, did he just sit in those Oracle ILT courses and stared from the window or did he just use some 3rd party monitoring tools in his previos work or was the work he did quite limited.

There is an OCP certificate that quite well shows what you know as a DBA. Passing those 5 exams (for 8i) means something!
