I burnt out helping a junior on my team for the past few months. It was just terribly obvious she was feeding my responses directly into a chatbot to fix instead of actually understanding the issue. I can’t really even blame her, there isn’t much incentive to actually learn
That sounds like a bad hire, not a junior. Why didn’t your manager help fix that?
I've been in situations like that. For me, it's like interviewing, I just keep backing off, lowering the bar, making it easier and easier until they can get it, then start going back up again. I pretty quickly get a confident read on where they are.
If at that point it's clear (to me) the situation is not salvageable, it's a management issue, I've done my job.
