Of course, bring a couple of copies, and be sure to read your resumé before the interview, so you’re completely familiar with everything you’ve written. Nothing is more embarrassing (or potentially fatal to your candidacy) than being quizzed on some aspect of your background that appears on the bottom of page two — and not being able to remember the details.
You might also bring materials that would be particularly good at illustrating an important aspect of your work, such as creative designs, writing samples, and so forth. Just remember to use your better judgment.
I once interviewed an engineer who brought with him a lawn and garden string trimmer made by his current company, so he could show me the design improvements he’d made on the product. It turns out his engineering efforts had lowered the trimmer’s cost to manufacture, which resulted in increased profits for his company. His version of “show and tell” was a bit extreme (my whole office was buzzing for weeks about my Weed Eater candidate), but at least his real-life picture told me a thousand words.
Be careful, though, not to overdo it with the props. College diplomas, letters of commendation, and company bowling trophies should be left at home. When in doubt, just bring your resumé and your business card — they’re the most important props you’ll ever need.
It’s a good idea to carry a leather folder or day runner with you so you can take notes or store written materials the company might hand you during the course of your interview. A briefcase is also fine, although I prefer a folder, which is lighter to carry, and less cumbersome. Always remember to bring a pen or pencil.
