Long story short I've been transitioning from IT / programming to teaching elementary computer / tech classes (currently working two part-time jobs, one in each field.) In elementary there are a variety of hybrid positions that involve some mixture of teaching classes to students, facilitating other teacher's tech needs, keeping hardware up and working, etc. My part-time teaching position is like this, and I love it, so I'm basically looking for something similar but full-time with benefits.
Anyway awhile back I applied for a position at a school that had a sort of vague techy description, thinking it might be one of those hybrid positions. Had a phone interview for it today and it turned out to be a regular tech support job without any teaching at all (and no teaching contract / benefits / etc.) Nonetheless I went through with the interview and it must have went well because they immediately called me back for an in-person interview. I wasn't prepared for this (was still processing what happened) and agreed to the interview.
However, upon taking time to think about it, I know for a fact I don't want this position. I got into teaching to teach, if I'm just going to take a tech job I could get paid much better finding a programming position. I do like the school / district though, and they obviously liked me enough to want a second interview, so I don't want to burn any bridges with them, in case they have a tech teaching position open up in the future.
I've been thinking of canceling the second interview before wasting more of our time, but since I already accepted it, that would make me look wishy washy, correct? However, I know that if I continue there is a very good likelihood they will offer me a job, and having to stop things even further into the process would look even worse. So cancelling now seems to me to be the ideal solution.
How should I go about this, however? Should I write a long email explaining how I'm really looking for a more teaching-oriented position? Or short with a more vague suggestion that I'm pursuing other options instead? I'm really not sure what the best way to proceed here is.
