How many ping-pong balls would it take to fill a 747?

June 11, 2014

ping-pongThere has been much in the press recently about weird and wonderful interview questions. The ping-pong ball dilemma being one of the best known. Incidentally if you want to know the answer it’s a remarkable 31 Million. However, if you want to win the gold star you also need to observe that the balls will all have a weight, and if the cabin and hold are filled completely, this will add up to a considerable tonnage. 83 Tonnes! The plane wouldn’t be able to take off. Okay, so now your brain is up to speed, here’s another:

Taller on the outside than the inside

WWIt seems like there is some truth in the expression ‘fake it until you make it’. Really! Could standing like Superman or Wonder Woman actually make you feel and look more powerful? The answer appears to be yes. Expansive, open body postures increase testosterone, decrease stress and make people feel more in control. And here’s the interesting bit, in a selection situation, especially when candidates have to give presentations, holding a more ‘powerful’ posture increases the chances of getting hired by 20%. So strike a pose before going in to an interview (it would be a bit weird if you struck up your Superman or Wonder Woman position when you were actually in the room), and stand tall when delivering a presentation. It could make a big difference.

The first 90 days

November 5, 2011

I was recently reading The Interview Question You Should Always Expect (HBR Blog), which as the title suggests is written from the perspective of the job candidate, and it reminded me that it’s also the killer question for any interviewer. Afterall it’s not where the candidate has come from that makes the difference, it’s what they’re planning to do next… Not sure what I’m talking about? Read the HBR article.
