Make the most of your professional references.
Always provide the pertinent contact details. There’s nothing more frustrating for an employer than trying to contact references with incorrect or outdated information. If they have to hunt down your references, you’re much more likely to wind up in the discard pile - wrong information projects (your) lack of attention to detail.
References should include company name, reference title, name, email, mailing address and phone. Also, include a quick blurb regarding your relationship to the reference.
