Testing Ability of a Candidate to Apply Knowledge in Practice
Jaap de Jonge, Editor, Netherlands
The way you formulated your question ("…during an interview") might perhaps be stopping some people from thinking in the right direction. A selection interview has its merits (it's simple and cheap), but testing a candidate's ability to apply knowledge in practice is not its strongest point.
Organizations wanting to do that could explore various forms of TESTING and/or having candidates solve CASES. (This could even be in TEAMS). However such approaches are considerably more complex and expensive.
Then again, what is expensive if we are talking about selecting key employees for the organization?
