Some employers ask for references upfront. Most don't. Furthermore, it is no longer necessary, and shows you haven't updated your resume skills in several years, to put 'available on request' on your resume--if you have them, of coursevtheyre available, and if you don't don't advertise you don'thave any! An employer for the most part won't bothervwith references if they don't like you in interview, and if they do will only then violate implied privacy of your refs, whondont wan to receive calls from everybody you sednd a resume to, which could b hundreds. Presumably if you decide in interview this job isn't for you, you withhold your refs again heir time and privacy, and say, no thanks.
