Consistency is a good weapon of influence in job-hunting — the idea being that if you make a public statement, there are strong pressures to stay consistent with that, both internal and external.
Let’s say you’ve got a job interview, and you know that you’re among a variety of candidates. Say something like, “I’m very pleased to be here, and I look forward to giving you all the information you’d need to know about me, but before we begin, would you mind telling me why it is that you selected me to interview.” And let them speak. Let them, in a public, active way, describe your plusses. And they will spend much of the rest of the meeting validating what they are on record as having valuing about you, because people want to stay consistent with what they’ve previously claimed.
