When you arrange the interview, find out who you’ll be talking to, and what their function is within the company. Will you be speaking with the hiring manager? The manager from another department? The personnel director? The internal recruiter? A peer level employee or subordinate? A staff industrial psychologist?
You might already know the person. If that’s the case, you’re ahead of the game. If not, send out feelers among your own contacts within your industry, or look in your industry’s trade publications to see if the person you’re going to be meeting is distinguished in any way.
It’s also helpful to find out whether you and the person you’ll be meeting have any commonalities or interconnecting points of interest, in the way of origins (“Hey, you’re also from Wisconsin?”), schools (“My brother went to Duke, too. How did you like it?”), professional achievements (“My article appeared in Ad Week a month after yours did.”), or personal interests (“I heard you were the Nebraska state ping pong champion. We’ll have to get together sometime for a match.”). These tidbits can break the ice when an interview begins, and create a bond with the interviewer.
