I burned out hard towards the end of last year as an engineer. Fortunately, this preceded 4 months of paternity leave during which I was really able to think hard about what I wanted out of my career. I came back to a different position at the same company, as a PM on a new team. I'm enjoying the role for now, but I'm not sure if I'll convert permanently. If I do go back to being a SWE, it will be at a smaller company/on a smaller team where shipping code takes less overhead.

Generally my advice to anyone feeling burned out these days is to take a long break if they can, and use that mental space to strategize your next move. I appreciate that not everyone is in a position to do this, though.
