Put about 100 bricks in some particular order in a closed room with an open window.

Then send 2 or 3  candidates in the room and close the door.

Leave them alone and come back  after 6 hours and then analyze the situation.

• If they are counting  the bricks - Put them in the accounts department.
• If they are recounting  them - Put them in auditing.
• If they have messed up the whole place with  the bricks - Put them in engineering.
• If they are arranging the  bricks in some strange order - Put them in planning.
• If they are  throwing the bricks at each other - Put them in operations.
• If they are  sleeping - Put them in security.
• If they have broken the bricks into  pieces - Put them in information technology.
• If they are sitting idle - Put them in human resources.
• If they say they have tried different combinations, yet not a brick has been moved - Put them in sales.
• If  they have already left for the day - Put them in marketing.
• If they are  staring out of the window - Put them on strategic planning.

And then last  but not least.

• If they are talking to each other and not a single brick has been moved?
  Congratulate them and put them in top management.
