How to sort new employees?

How to sort employees so that they’re fulfilling their job potential? We don’t have Harry Potter’s Sorting Hat, so here's the alternatives:

Put 500 bricks in a room. Ask all the new employees to go inside the room, then close the door, go back after 4 hours and check on them.

1. If they’re counting the bricks, they should be in the Accounting Department.

2. If they’re counting the bricks a second time, they should go into Auditing.

3. If they have put the bricks all over the place in donno what funny order, then they should be in the Engineering Department.

4. If they’re staring out the window, they belong in the Strategic Planning Division.

5. If they are arguing over who should do what about the bricks, then put them in the Legal Department.

6. If they are sleeping, they should go into Security.

7. If they say they have tried putting the bricks into all sorts of combinations, but honestly, it looks as if nothing has been moved – these guys should definitely be in Sales & Marketing.

8. If they are checking Wikipedia for what to do with the bricks, they belong in I.T. Services.

9. If they have already gone home for the day, they should be in the P.R. team.

10. If they’re sitting around and talking cock and drinking kopi, not doing anything, then they should be promoted to Senior Management.

11. If they have piled the bricks around them like a fortress and you can’t see them, then tell them to join the Civil Service!!!
