Having tried to drink from the firehose in the past, I can say that I have never once had a recruiter lead actually result in a job offer. It's one gigantic catch-22. The companies themselves aren't great at hiring, or they wouldn't need to use recruiters doing semi-random searches on linkedin. If you yourself were any good at interviewing, you wouldn't need to rely on the recruiters either. You're an unqualified lead that can't get a job on his own, which to a hiring manager screams "high risk hire." So you start the interview process in the negative column and have to really shine to get a job offer. But, if you were any good an shining in an interview, you wouldn't need the recruiter in the first place. The whole thing becomes a high stress waste of time.
