Related anecdote: There was a technology recruiter that was constantly calling me at work, despite the fact that my work number is not listed anywhere* and my LinkedIn profile having clear instructions not to do that.
I decided to look him up on LinkedIn. Guess what his previous job was? Debt collector.
* I figure the recruiters get around that by calling the front desk and asking to be transferred to me.
The best recruiters can not only make efficient matches, but they also connect the dots to reach out to matches in the pool of passive candidates they talked to when a new role opens up.
Even better than that is when I'm able to actual push back with companies and make an impact on the hiring process to get someone hired.
With that foundation I'm more effective as I see more career trajectory data points when I talk to candidates that specialize (data, security, devops, ml) or ladder up (vp, manager, cto). Then I can provide even more value to new candidates with the career counseling approach.
I work with about 70 companies (only in NYC) from pre-launch to almost IPO and a new role opens up to a us every week. It's helpful to find a recruiter who knows you & the market well enough to curate jobs you want and tell you about opportunities that might not even be listed or on your radar.
