The “Corner Office” column in the 11/11/12 Sunday New York Times featured Jeff Weiner, the chief executive of LinkedIn.

Within that column are two points about questioning that are worth noting. First, Wiener advised people starting their career to spend some time thinking about a very basic, fundamental question: “Looking back on your career 20, 30 years from now, what do you want to say you’ve accomplished?”

Seems like an obvious one, right? But Wiener says, “You’d be amazed how many people I meet who don’t have the answer to the question. They either never asked themselves that or they got swept up in a stream of opportunity that led from one thing to another—more titles, more money—and they just didn’t stop to ask themselves that simple question.”

So be forewarned: If you ever interview at LinkedIn, Jeff Wiener is going to ask you this question and you’d better be prepared. And even if you never plan to interview at Linkedin, it’s a question worth spending some time on.
