For my industry, IT, pretty well. A nice upward career trajectory and an average of about a month from search start to offer over the past couple of jobs
It worked fine for me, I've landed three jobs that way. That was a while ago though, the last time was in 2017. My last two jobs I took because I had some connections call out of the blue. I've been very fortunate in that regard. I can't imagine that would happen again, most of my connections are getting close to retirement age at this point.
