This week's KIQ comes from Disrupt CEO Gary Elphick: "If I call up your current employer right now what three things are they going to say about you?" (Tread carefully: they might actually ring up.)

This week’s KIQ is a present-day twist on the "where do you want to be?" question. It forces the applicant to assess their lot in life and reflect on the paths that led to this moment. Deep.

Today's KIQ could be construed as somewhat intrusive - even nosy. However, their answer (or non answer, as the case may be) will reveal a lot about an applicant's suitability and values.

"What do you consider to be your biggest weakness?" Most job applicants have encountered this interview question multiple times. They have subsequently become adept at dodging it completely. Usually, this is achieved by dressing up a positive attribute as a "weakness". To force a more honest answer, try adding the above disclaimer.

Sometimes, it's the simplest questions that provide the most insightful answers. Asking a job applicant to explain what they know about your company will reveal their level of perception and passion for the business -- as well as whether they bothered to do any homework.

Asking potential job candidates to dwell on past regrets might seem a tad rude. But the answer can be fruitful on a number of levels. A good response will reveal how they judge their career to this point, how they personally measure success and what their ambitions for the future are.

This week's KIQ encourages you to speak up.
