When my friends ask me for interview advice, I always say - "If the Interviewer wants to do most of the talking, let them. They're going to end the interview and think it went great..."
Now flip that around. Smart interviewers get a candidate talking and let them go. They pop in and out to clarify, to ask for more, redirect when it's all BS and generally keep the session in between the ditches.
Want to see what the type of info someone can get when they let the subject do all the talking and generally get them more comfortable than they should be?
Ladies and Gentleman - I give you the father of Texas A&M star Johnny Manziel, aka Johnny Football. More pulled from the Wright Thompson ESPN Article via Deadspin:
"Not long ago, backstage at a country music concert, the two Manziels hung out with some of Johnny's friends. There was Uncle Nate, a high school teammate named Bryan and Johnny's buddy Colton from College Station. Everyone stood around, the band warming up. Without so much as a nod, the Crotch Shot Ninjas struck: Paul punched Nate in the nuts, and, simultaneously, Johnny kicked Bryan and hit Colton, both in the balls, both at the same time, and as the three dudes doubled over and the band howled in laughter, Johnny and Paul gave each other a fist bump. Mission accomplished."
So Thompson is interviewing Paul, the father of Johnny. I'm guessing after about 8 hours of being comfortable, Paul's telling stories, and this is one he's proud of. <sigh>
To much piling on related to Johnny Football, but this is the one that caught my eye. The dad, stories of Crotch Shot Ninjas. We're friends! Father and Son!
And this, my friends, is why it is the interviewer's job to let you talk. As much as they possible can. Because you get comfortable, and the interviewer gets negiative information. Sure, it might take hours, but isn't it worth it?
