Dealing with this now at work. Got a dev whose time in the industry should make him a senior dev but he gives off massive junior vibes.

• The need to change everything he touches

• Wanting to write clever code over straightforward code

• Everything “needs” a refactor

• Just deprecates things when he doesn’t want to learn them and writes a new implementation without updating old code

• Thinks he knows best while not understanding huge swaths of the codebase

• Everything he can’t understand in <5 min is stupid and wrong

If he was less competent (when kept in a box and closely monitored) I’d be pushing even harder to get rid of him.
