In a good and healthy interview, the interviewer should talk about a third of the time so that there is some give and take. The candidate has to be sure to answer the questions asked and not give too much information.
I met an account director who I liked a lot. I sent him to an agency where the Director of Human Resources was both a client and a friend. I thought they would like each other and there was an appropriate opening at the agency.
My candidate must have gotten nervous. I have learned that talking too much is a sign of nervousness and is a form of control. If one talks a lot, then the other person cannot speak enough to have control.
But talking too much and answering more than you were asked, can backfire.
The head of HR asked my candidate to tell him about himself. And so, my candidate did….
It seems he was a twin. His brother got the good grades in school. His brother was better looking and got the girls. The brother was chosen for teams first. They both went to Ivy colleges, although my candidate felt that his brother got the better education. The candidate went on to talk about his career, which was excellent, although he did talk about his brother’s career in slightly jealous tones (the brother was not in advertising).
The candidate called me afterwards to tell me that he thought the interview went well; it had lasted about forty minutes and he was anxious for next steps.
I called my client for feedback. Indeed, the interview went for about forty minutes, but the HR Director told me that the candidate talked for about 35 minutes. He told me that the candidate had spent the bulk of that time talking about his twin.
At the end of the debrief, my client asked me if I could recruit the brother….
You just can’t make this stuff up.
