Cold messaged someone on LinkedIn who'd never met me and it turned into a referral three weeks later

Sent a short message to someone at a company I wanted in, just asked one specific question about their team's stack instead of the usual 'any advice for someone trying to break in.' They actually answered, we went back and forth a few times over two weeks, and they offered to refer me before I even asked. Think the specificity is what got a reply at all.
