So you read our guide on improving your subject-matter-expert interviewing skills and now you think you’re ready to rock your next thought leadership interview. If you follow our advice, you probably are. But even though you know what you should do, you also need to know what you should not do to get the best, juiciest, most innovative ideas and quotes from the architect, engineer or construction pro you’re speaking with.

I can’t teach you to be Oprah, but I can help you optimize your interviewing strategy by avoiding these nine mistakes.
