Hello,

I have a 2-hour long Hackerrank test coming up for McKinsey Analytics. I was wondering how the correction is done. Is the code reviewed by a human (therefore I would need to comment it properly), or is it an automatic answer-correctness test (in which case I just have to worry about getting the right output) ?
Thank you!

Hi Aymeric,

My understanding is that this is a multiple choice test.

As in, there are sections you have to code on your own SQL Studio, Python IDE, etc. but all you're doing is getting the output and selecting the right answer.

As such, you should not need to comment in your code.

Given that speed is the constraint AND we do not need to hand this code off to another devleoper or keep it forward compatible, I think it's safe to not include comments in your code.
