They asked me if I worked on individual projects besides the ones that I had to do for school. I answered no, because I didn't, but is it that bad that I had to give that answer?
Well, it would have been a plus to say that as a part time thing you've designed the software for one of the robots NASA sent to Mars.

Are all companies like that, leaving you in suspense?
Aren't they supposed to say "we'll call you!" and then never call if they don't want to? Maybe it's better this way though. They didn't say "we'll call you", but
they will.

In all, what's done is done. All you can do now is wait, hope the other candidates did worse, and keep look for other job opportunities.
