I was in the sameish boat, meaning I'm still an imposter, but I took one promotion too much. And it burnt me like crazy.

0/10 do not recommend, cried for weeks while hiding under my blanket. The main issue was that I tried to do a good job, but I was just not able to perform in this position.

The happy ending, or at least a happy midterm goal, was that I switched lanes and now perform better in a different job. But taking every promotion that is offered to you can be an error.
