You contract with an outside firm to do the interviewing, screening, etc. On the other hand, a completely separate HR department gathers the prerequisites of the hiring department or manager, and then they make the decision as to whom to hire. The manager is given a new worker with no biased input as to race, gender, sexuality, attraction, etc. I think it goes much further than simply having a workforce that works well together, and likes to hang out with each other. The attractiveness of the candidate, and whether or not they&#x27;d be fun to hang out with on the weekends, or worse, date, should have zero bearing on the hiring process.<p>Check out Malcolm Gladwell in his book &quot;Blink&quot; discussing blind auditions for musicians.<p>Also: <a href="http:&#x2F;&#x2F;www.theguardian.com&#x2F;women-in-leadership&#x2F;2013&#x2F;oct&#x2F;14&#x2F;blind-auditions-orchestras-gender-bias" rel="nofollow">http:&#x2F;&#x2F;www.theguardian.com&#x2F;women-in-leadership&#x2F;2013&#x2F;oct&#x2F;14&#x2F;b...</a>
