Sure, deciding why to let someone go is up to the company or manager. Firing someone isn't the huge deal, the reasons for firing them certainly can be. With development, you can actually have negative productivity. An example would be spending money to un-hose what the developer did years after they've left. If enough stuff was built on top of a mistake, it's unfeasible to fix. Bad design decisions tend to lead to other bad design decisions. I'm dealing with a lot of that where I am now. I think part of the reason these tech interviews are so absurd is people are emotionally terrified of firing people, so they take great pains to ensure they won't have to. I'm just speculating though.
