I'm in the job market and I've hit a lot of these Hackerrank style tests.
They're easy. They (the people writing and administrating) the tests bend over backwards to offer the same test in many different languages. They provide unit tests and examples.
To be quite blunt: These tests just verify very basic programming skills. They're meant to filter out people who just can't code. Someone who's struggling with these kinds of tests probably needs to consider a career change.
Edit: A common gripe early in my career was the amount of incapable programmers we had to put up with. I suspect the author isn't capable of learning how to program well.
