336 is correct. If candidate 1 takes the first seat, you have 7 candidates to take seat two, and for each of the seven candidates you have 6 more to take seat three. So whichever of the candidates takes the first seat gives 42 possibilities for the remaining candidates to take the other. 42 * 8 = 336.

or 8 permutate 3. (8*7*6 as stated above)
