I`ve hired a bunch of people in my day, some bad, mostly good. But I haven`t made even one bad hiring decision since starting to religiously follow this single rule: No matter how qualified the person, how well-suited to the job, or how well I hit it off with him or her, I never, ever hire anyone without checking his or her references - three at least (4 or 5 is even better). If the references don`t speak about the candidate in absolutely glowing terms, I don`t hire the person, period.
By the way, I`m always sure to ask questions that would invite any doubts or negatives to come out in a way that seems like it wouldn`t hurt the candidate. For example, first ask: "What would you say are John Doe`s strengths?" then,
"Everyone has areas where they can improve. What are John Doe`s areas for improvement." The other question I always ask, and I think it`s the most telling, is, "Would you hire John Doe again?" On this question, anything less than an immediate and firm yes is reason to pass on the candidate.
Good Luck!
