Drop Dead Simple Interview Questions

[Ofnuts]

I wouldn't ever give Fizzbuzz, I'd be afraid of insulting the candidate. Are you interviewing them for a specific role or position? Are they expected to be familiar with computer science?

A warmup question I often give is "write a function which takes in a string and returns true if the string represents a number." The candidate is meant to clarify the requirements, and be able to code it up after. If they write something that just handles non-negative integers, I start providing additional sample cases for negative and floating point numbers. They also often don't accommodate for "-", "." and sometimes even after that, "-.".

Well, you didn't think about the thousands separators either. And this question is more complicated than you think.
