If you genuinely explore this question and try to find out what you would like to be doing in 5 years time, you can increase your chances of making it happen.

Rather than an unfair trick played on us by interviewers - as it has been called by some in the past (myself probably included) - this question can become something that we can't wait to be asked. It could even become a question we feel privileged to be asked and have someone listen intently to our answer.
It is in our own hands to create a response to this question that is not only clear and incisive but also compelling to our audience whoever they may be.
When we can answer this question for ourselves, it proves that we not only know where we are heading but what we are depending on to get us there - and from a career management perspective - that is a pretty good place to be!
