> simple ones like FizzBuzz where it's just a quick filter

I stumbled across a thread in r/cscareerquestions or maybe r/cscareers a while ago where several people argued that fizzbuzz was too hard because: "no-one is using the modulus operator in day to day work, so it's not something one should be expected to remember."

I found it very funny and draining at the same time.

I just grepped through a 250,000 line project on my system and I had only used the modulus operator six times.

I'd still expect a programmer to know it but that should be tempered by the fact there will be parts of the technology stack you are intimately familiar with that another person might barely use and vice versa.

The company that used FizzBuzz had a rule that we’d give the candidate an explanation of the modulus operator if they weren’t familiar or didn’t remember.

It didn’t change anything.
