Animation folks: I'm curious how many of you actually broke into the industry through online/public job postings?

I've heard so many recent grads ask the basic question of: "Where do I go to apply to jobs?" and I kind of don't know how to valuably answer them.

Full-time jobs I've gotten through online postings: 0
I got all my internships through online postings, but I'm not sure how much that counts because I often met the hiring folks at least casually at job fairs beforehand

For those curious, I got my first full-time gig (Gravity Falls) because I randomly heard a rumor from a classmate that they might be hiring, who encouraged me to contact a former teacher who had done character design work, who in turn gave me the email to the line producer

That ultimately led me to getting a storyboard test, and I know like? 30? people or so tested for the same spot? but I'm not sure if the job position was ever listed online or how many people tested through that process.

Given that so many of us learned about jobs through friends/classmates.... what would you tell a recent grad without contacts in the industry? 'Networking' is such a vague concept, and we ALL know people who do networking the WRONG way and end up looking 'sleazy'/'fake'
