You sometimes have to be careful and look if people are overthinking the problem. I have been in interviews where I was desperately looking for an efficient solution for a problem and couldn't find one while the interviewer only wanted to get a simple for loop.

Having sat in that interview he wasn't overthinking it. Despite writing firmware for decades he had never heard of the modulus operator, and when we explained it to him, he didn't see the point of it.

Remember those people in college who contributed nothing to the group project, but still somehow squeked by with a C? Those people now have jobs, and some have impressive resumes, particularly from .gov contractors where less than mediocrity reigns unfettered.

I know the modulus operator but I don't recall ever using it in more than 20 years :)

Are you a firmware dev?

Nope. Do firmware devs need modulo? I thought they do everything with XOR.

[monocasa]

Yes, it comes up a surprising amount.
