I mean, I guess. Kind of arbitrary really, I don't think it matters in terms of precision one way or another.

-6.5 is closer to -7 than it is -6 because I said so.

Do I get the job?

-6.5 rounded up is -7. I am of course treating "up" in the context of a vector pointed towards the negative direction. QED.
What do I win?

You need to learn about machine precision. Type in
0.1 + 0.1 + 0.1 == 0.3

You can't round -6.5. You also can't round 6.5. You can only round |6.5|, which is |7|
