Overconfident, but also easy to sway their opinion.

They follow directions for maybe an hour and then go off and fix random shit because they forgot what their main task was.

They'll tell you to your face how great your ideas were, and that you're absolutely right about something, then go implement it completely incorrectly.

They add comments to literally everything even when you ask them to stop. But they also ignore said comments sometimes.

Maybe they are kinda like us lol.
