Subject: Re: Programming Test Invitation

Hi there! Thanks for offering to let me take a HackerRank test for ABC, I appreciate the vote of confidence.

I'd never heard of HackerRank, but after you wrote two other employers sent me their own HackerRank tests. Having worked on those tests first (I considered them practice, for the real thing with ABC :), I'd like to check if you have flexibility in finding an alternative way to evaluate my basic coding chops.

This is because, as functional programmer and author Paul Chiusano says, "Programming is all about managing complexity" [1], but HackerRank is quite bad at measuring my ability to manage complexity. It asks for small algorithmic coding puzzles to be done in unnatural conditions including (1) time limits, (2) forbidding research on Wikipedia or StackOverflow, (3) forbidding collaboration, and (4) forbidding the use of libraries (Python and JavaScript e.g. are so different when confined to thei
