Wasted Time?

I keep trying to get a job and go on interviews, but it's a struggle and I wonder if it's even worth my time.

Today I went on an interview.  The principal told me that the NYC DOE has a hiring freeze on out-of-system teachers (unless you carry a certification in Special Ed., science, or math).  I was shocked.  Then he asked if no one had previously told me.  Obviously not.  Really, it costs 30 bucks to get into the city per interview.  Would I do that for a job that was not available?????

Well, the good news is that the man who interviewed me today said he received a call last Friday from the big office suggesting that they may be opening the door for new hires.  Hmmmm....perhaps it's not been wasted time.  In fact, the principal told me I did a good interview.

Please, let it not all have been wasted time.
