I had in mind someone who's been in at least a couple companies (megacorps, startups, something in between in terms of size, tech companies but also regular "boring" businesses like a bank), has some tech lead experience (or is at least very influential in his team). In other words, someone who had enough opportunity to see what flavors of the job are available and what it really entails. As for the purpose, I mostly included it in my question to specifically not get answers from less experienced people, who may still be in their honeymoon period. The background here is that I am in a job that will allow me to retire in 5 years (and nothing else pays even close in my country) but is so mind-bogglingly nonsensical that I wonder if it would make sense to change it to something satisfying even if it having to work much longer.
