Way to add to the conversation. Hiring your "buddies" is WAY lower risk that acqui-hiring strangers. They are a known quantity AND they have enough loyalty that they probably won't bolt the instant they are able. They'll also probably work harder for you than the average acquihire. This is how the world works-- and it makes sense. It isn't just bullshit "who you know rather than what you know". Moral of the story is…
All you say is correct, even down to the "it's who you know line", but I disagree that we should exploit it or even tolerate it. It's just Cronyism ( https://en.wikipedia.org/wiki/Cronyism ) and my personal moral compass rejects it.
The main question then becomes, were they hired more for relationship and connection or because of their credentials and experience?
