Yes there is a common theme of not “bringing people along”.

Yeah I'm not sure what an onboarding tool is going to do for a guy who gets hired, decides from day 1 that he must be promoted immediately, makes other peoples' lives miserable by showing to his manager that he's "aggressively" doing something before he even understands what's going on, and whines constantly about not being promoted within a few months.

It’s like the lesson told in the paragraph above “this is what my team did” and imply “and I am their manager”. This is what I learned and imply “and I can help you learn too”
