I’m interviewing for some positions in my team and one external candidate has been a red flag. They were referred by another colleague. This individual has been very vocal about the interview process and chasing members of the team constantly for updates. I suspect they will be one of those difficult people to manage going by pre interview behaviour! However I have a feeling they will do well in the interview having intel from their referral friend. I will be fair and objective but I don’t want this person joining. How do I manage this if the person scores well / above others?
