I interview 20-30 people per week and send most of them Hackerrank tests. I'm a big proponent of vetting that people can write code, but 99% of the questions on HR are waaaay too "algorithmic". Had to go through almost all of them to find a few tests that are not about graph algos or dynamic programming – finally found a question that was based on regular expressions and a few other ones that I think are a bit more representative of real world challenges.

I really wish Hackerrank could add more problems or let employers add their own question. Are there any good alternatives to HR?
