interview coaching?

Hi,
I'm headed into my second interview and I'm wondering what are some common interview questions, or areas I should concentrate on as I brush up?
I'm self taught in AS2, though I have a background in C++, from years ago. I'm currently at my job of 1.5 years at a small company where I can (and do) get away with programming without OOP. Obviously all the work will be OOP at the new job, but the few times I've programmed using it, I've had no trouble.
I only ask because I was recently rattled by a smaller company's interview which I suspect was a little unconventional but I'm not experienced enough to be certain - a quiz about big O notation, algorithms, etc, during which I was to answer on a dry erase board as they asked, rather than given time on my own to plow through it. Is this kind of interview normal? As a C++ programmer, are there any major differences in how AS2 works that I should know about?
I know I'm probably not as knowledgeable about AS2 programming as they'd like me to be, but I'm confident I can learn quickly if there's anything I don't know - that's part of the reason I'm interested in the job. Unfortunately, I don't think bigger companies will be willing to put their faith in a stranger so easily!
Help? I'M FREAKING OUT HERE. :scared:

That interview wasn't normal.

Normal is being asked to show examples of your code and or work and being asked to explain how it all works. I've had a written test once, but that was on paper and I was left to do it myself.

From a coding viewpoint, sell the fact that you came from a c++ background, as that's a more difficult language.

Your main weakness that might be a lack of flash build/animation/cretaive skills, but it really depends what the job is for. Some are heavy on creative, some prefer purely good coding.

If you don't want to talk publicly, pm me, let me know the company/position you're applying for and I might be able to give you some more pointers.

I get interviewed quite often as I'm freelance, got one coming up later today in fact.
