Before you even get to the interview, Brooks says you should watch the way you ask for a person’s time. Too many students are overly casual, writing, “Hey Bill, I’d like to talk to you.” Better to err on the formal side, unless the person is close to you in age: “Dear Mr. Smith, I was wondering if you’d be able to give me 10 minutes of your time on the phone for an informational interview.” I’m 56 and personally I prefer an informal “Hi Susan,” but I take her point. She recommends the phone because it’s the least trouble for the interviewee and often the student is in school in another city.
