This is true for smaller companies, that hire for targeted roles, take the time to write good job descriptions and may even think a bit about what they are doing, because every person they hire makes or breaks the company.

The moment a company enters growth phase and they need a lot of talent, nearly everything goes out of the window. Most (not all) job descriptions become generic and less thoughtful and they resort to generic technical questions in interviews, simply because there aren't that many candidates who have relevant backgrounds (e.g. I need someone to work on deployment systems, but you have payment systems background) and they can't wait forever.

Obviously there are exceptions on both sides, but this is generally how it pans out, in my experience.
