> if you have years or decades of experience you should have a large network of colleagues

yes, but more often than not, those colleagues best interest is not YOU but their employee referral :) .

At least in my experience, they often try to oversell the company they work at, as the best place to work, trying to get you to join, even if they know it is crap.

I do my own research and always take "ex-colleagues" advises with a grain of salt, basically I mainly trust my judgement, balance sheets for public companies and buzz around like glassdoor, blind, etc .. :)
