No I dont tell anyone I have interviews after them even if I do or do not. My biz is run on a first come first serve basis's. I dont give out my reference numbers until after I have an interview. I phone them or e-mail it to them after I decide whether they are a fit or not here, its not just their decision. I wouldnt worry about them bad mouthing u if your references know you well or have been in your care they know shes a liar.
