> This is typical technical jargon conflation in furtherance of interview pedantry. That's an interesting point of view. I thought it was just an article explaining what covariance and contravariance are in the context of a type system. The author also went so far as to give some illustrative examples. The author could have just copied the definition from the dictionary. It seems like that would have been sufficient for you but it's unlikely that it would have been helpful for the majority of people that work in type systems and aren't aware of the more general concepts they work with. The author never mentioned anything about interview techniques.
