As someone who has been on both sides of the table, I don't really know what some 45 minute HackerRank test is supposed to demonstrate that can't be learned in a 10 minute modified FizzBuzz. Probably 95% of software development jobs don't need the kind of algorithmic expertise that these HackerRank problems try to test. There just needs to be confirmation that this person's resume isn't a complete lie and they actually have the skills it states.
