Interviewer: “Now that you’ve seen the site, would you be ready to sign up now, or do you need more information?” Customer: “Um, I guess I’d need more info . . . Oh, here’s the FAQ. I’ll check it out.” This exchange looks okay at a glance, but the multiple-choice question (“ready to sign up” versus “need more information”) has influenced the customer’s response. You’re assuming that the customer wants to do one of those two options. It’s tough to do, but you should avoid asking multiple-choice questions. They’re almost always leading questions in disguise.
