It is helpful for you keep in mind that just as you wish to get the facts about the candidates they want to know the truth about your firm and the team in which they are going to work. If you misrepresent the nature of the work and its challenges, or the firm’s policies and culture, then this will become apparent very quickly to those who join you. Motivation, and therefore performance, will immediately take a knock. The selection process works best when the selectors are completely honest.
It is also important to remember that when you are involved in recruiting new people you are in effect seen by the applicants as an ambassador for your firm. Treating candidates in a dignified manner, and in particular ensuring that those who fail to make the grade receive thanks for their interest and a clear explanation for their rejection, is imperative. People who are treated in a cavalier fashion may have some very harsh things to say to others about the firm concerned.
