Yeah...teh failure to follow your basic request to call would be a red flag to me. I once followed through with an interview for a parent like this. It took me several emails back and forth to get her to actually call me (and I debated not pursuing it because of this). Then after the interview she called and wanted to negotiate my contract...she didn't think I should have paid vacation days, stats etc since she is self-employed as well and doesn't get these. Finally I decided to fill the spot with the other family I had interviewed...I don't want to have to work so hard to establis basic communication and I don't want someone coming in and trying to change my policies on me.
