The names of the candidates can be printed in P(6, 6) or 6! ways
Intuition:
For the first place, we have 6 choices.
For the second place, we have 5 choices.
For the third place, we have 4 choices.
For the fourth place, we have 3 choices.
For the fifth place, we have 2 choices.
For the sixth place, we have 1 choice.
Therefore, total number of ways = $6\times5\times4\times3\times2\times1$
