this is a bullshit problem.

i've got an I.Q. of 154 and i can't fucking figure this out. i'm probably just too distracted to come up with something.. i'm playing battlefront, muahahaha

150, sorry.. my dad has 154... figures.. he owns a fucking print shop. intelligence never seems to end up where it should.

doesnt work, burns inconsistantly.

I am not getting the point to burning the rope. Use it for something constructive and burn the car you just wrecked.

the point of the burning rope exercise is to demonstrate mental problem-solving capacity to the interviewer, as well as to give the interviewee an example of the sorts of problems they're going to encounter as a software support engineer.

this particular part of the rope problem is also used to suggest another aspect of the puzzle-solving business: the possibility that there is no solution. faced with this option, many of the applicants opted for it quickly, others refused to accept it - neither of which is good neccessarily. of course, you see that there is a solution.
