While it makes sense to give former bosses as references, listing them over other people could cost you a critical advantage in the job search, according to ResumeWriting.com Blog.
Bosses of current competitors who admire your work make the perfect references. This shows potential employers you are a powerful force in your industry and know people they might like to connect with.
Employees who know you and work at the company where you are applying make great references. Their boss trusts them, and their word can put you above the competition.
Job references aren’t just about verifying sanity but can provide networking opportunities. List as references the people you know your interviewer would like to get to know.
Regular clients also make for good references. Your new employers might value those contacts, and taking you on would be a good way to get them.
