Personally, I dislike competitive programming interview problems. Competitive programming, when viewed as a sport, requires training and practice. It's a muscle that you must constantly train. If you stop for a few months, it may take you a few days or weeks to get back to the previous level.

So it's always frustrating to find a new job because I know I'll have to spend weeks practicing on problems that will have no relevance to the posts I'm applying to. To me, it's a waste of time.

I think companies that uses competitive programming problems (that are irrelevant to their engineers' day-to-day jobs) end up hiring people who are very good at interviews and perhaps not as good at their actual jobs.

Of course, there are jobs which deals heavily with algorithms and optimizations, for which these types of interviews are relevant. But the article is not talking about these relevant cases.
