New to Java

I have to sit in on 2 interviews today with people that are we are trying to get to fill a lead/senior java developer position.

My background isn't really in Java (small amount a few years ago), so I don't have all of the answers, but do understand the concepts/syntax, but I'm sitting in to get more of a feel as to how this person will do within our team.

The job itself will require extensive object modeling, and good interpersonal team/client skills, as well as being a top-notch developer.

What I'd like some help with, is coming up with some questions/answers that I may be able to pose to these interviewees that lead/senior people should know the answer to. I know the possibilities are endless, but any help you can provide is greatly appreciated.


Thanks in advance for your time and assistance.
