I'm going to push back on this otherwise excellent answer a little bit and raise the issue of company culture. While personal issues shouldn't--in the ideal sense--impact the workplace, knowingly bringing them into the fold could negatively impact the company as a whole. Be it frosty relations between two employees causing others to take sides and create division where none existed previously or direct confrontations that interrupt all other parties. All hires bear risk that they won't fit it in or they'll have a hard time adapting to company culture. Knowingly bringing in someone with strong personal issues with another employee should require a higher level of scrutiny to ensure the issues won't result in a toxic workplace or destroy internal culture.
