Harriet Green conducts an awful lot of job interviews.
As the general manager of IBM's Watson Internet of Things, customer engagement and education, Green is building a team that will eventually include more than 1,000 people and operate in the group's new headquarters in Munich, Germany.
A seasoned businesswoman and former CEO, Green has heard her share of glib answers when interviewing job candidates. To get past that she likes to throw a curve ball, asking every candidate this unique question, regardless of their background or expertise:
"The person who knows you best in the whole world, in their voice, what would they say is great about you and differentiates you? And what makes you a complete pain in the ass?"
Interviewees are almost always surprised by the question. But that's part of Green's strategy.
