If you want to know what competitive programming is, you won’t find the answer in a standard dictionary. Instead, you could look on Wikipedia. It’s not the most hospitable site for competitive programming content, and the main competitive programming article is rudimentary at best. But at least there’s an article, and it hasn’t been deleted […]

One of the many complaints that people have about coding interviews is that they are biased towards recent graduates. As the argument goes, recent graduates have just finished studying the algorithm-heavy topics that those interviews favor, so they have an unfair advantage.
