> I wish Sahat had reached out to more of his network before responding to random recruiters. Has his network moved forward in what they do?

Not precisely positions of power which I can take advantage of for the next step forward in my career.
You do not need to be in position of power to refer someone.
Otherwise, a reference will only add to the burden you have to overcome with the interviewers - they will consider not only your qualities, but the referrer's qualities as well.
