Rarely have I seen a question that would cause me to leave an interview unfinished. This one would do that.

(0! + 0! + 0! + 0!)! = 24

Well there are 24 different possible combinations - assuming the 0's are different

4 * 3 * 2 * 1 = 24

is this incorrect for me to use this as a solution?

This is what I was trying to convey - I guess he's the big winner!

Would HR be able to judge if the answer was right or wrong?

(((0!)+(0!))^((0!)+(0!)))! =(2^2)! =4! =24

!(0^(0^(0^0))) = 24 ; if you believe 0^0 is 1 that is...

That's not true even under your assertion

    0^0 = 1
    0^(0^0) = 0^1 = 0
    0^(0^(0^0)) = 0^0 = 1
    !(0^(0^(0^0))) = 1! = 1

Indeed. Oops
