Flash and Photoshop practice test?

Kinda depends on what the interview is for. Are you interviewing for a typesetting job, web dev job, prepress job, animated presentations job? The test can differ greatly depending on what youre interviewing for. Figure that if you know what youre doing, and know how to use those two programs adequately, youll be prepared for anything. If you dont know those programs adequately, perhaps the job isnt for you as itll just lead to a mess when they ask you to do something you dont know.

Thanks for the input.  Could you up with a few questions that the average Photoshop user would not know the answer to?

To pick a few would be nuts. There are so many intricacies of Photoshop that many experts dont even know about, much less average photoshop users. It all depends on what youre trying to do, with what, and where it's destined.

Thanks for the advice.  I am just interested in figuring out where my friend's skill level is.  He is the one going for job interview.
