Recruiters wouldn't be so annoying if they actually took the time to see if I were a fit for the position. Why are you wasting my time about a C# .Net position when that is not listed anywhere on my LinkedIn? Another thing I've noticed recently is recruiters telling me they have some "great positions" for me, but not giving me ANY information. They try to aggressively set up a call. When I press them for details first, they begrudgingly tell me. When I let them know that none of those jobs is a fit they drop all communication. How brutally unprofessional! Real-life example: # Communication starts Recruiter: Hi again! I hope this message finds you well! Your background is an ideal fit for this role! I would love to tell you more about us! Are you open to finding out more about the role? Me: Sure, what can you tell me about this opportunity? Recruiter: Hi! I can tell you everything over the phone if thats ok with you? I am not suppose to share details over the internet :( I am free today at 2pm EST if that would work for you? if so, do you mind sending your resume and best phone number? Me: Do you have a brief job description you can provide? Recruiter: This is all im allowed to share online: "big data web scraping and analytics tech company that helps brands such as Nike, Rolex and Sperry Shoes with online price monitoring, online brand protection and online price enforcement! The company was founded in 2004, they are incredibly stable, and profitable." i can share everything else over the phone if youre still interested Me: where are they located, at least roughly? Recruiter: it is 100% remote. they have a HQ on west coast and East coast. Me: technologies required? Recruiter: Backend development. primarily node Me: okay, i don't have much experience with node Recruiter: ok, they require 2 years or so. not that much? Me: Unfortunately not # Communication ends. What a horrible industry. I'll never go through a recruiter again if I can avoid it. Just garbage. Not even a "okay i'll try and find a better fit for you." They deserve to be treated the way they are.
