I get a lot (2-3 a week) LinkedIn messages from "cold calling" recruiters. I've answered to a few, set up 30 minute meetings, but in every case I either never hear from them again, or I get a nicely worded rejection email.
What's the "success rate" for people who answer these? I've met with at least 10 in the last 8 months and none ended with a job proposal. None of them has ever given me a real reason why (honestly, after making me waste 30 minutes with them, I'd at least expect some courtesy of giving feedback, but it doesn't seem to be something these people do).
In the same timeframe, I've applied for a company that led me through a 2-week (on and off) recruitment process and ended up offering me a Senior position after an "impressive" hiring process. All very impressive but the salary was about the same as my current job, and I'd lose all of my benefits.
So, I'm very confident about my abilities, but I don't seem to impress these cold-callers. Should I keep bothering with them, or are they a waste of time?
