How to conduct a great interview? Do something practical.

The best way to find out if somebody can do something well is to give them the chance to do it. While this isn’t always possible at the interview stage, you do have the opportunity to get candidates to carry out practical tasks. Better still, have a conversation with them while you do something new together. You can see how they interact, collaborate and react to a new challenge. Generally, you can get a glimpse at their character.
