There is nothing more frustrating then to spend hours meeting with a potential candidate only to find out that they were window shopping or seeing what is out there with no real intent on making a move. So, how do we prevent or decrease the percentage of time spent with candidates like this? Simply by asking this question:

Why at this point of your career are you open to other opportunities?

We are looking for a thread of discontent at their current employer. The answer given to this question must satisfy your belief that your candidate has a real reason for wanting to make a move at this time, if not, save yourself a lot of time and end the interview process.

Unravel that thread of discontent to uncover why they are open to opportunities and with this information, it can be used to your benefit in providing a solution which will attract them to your company.
