How do I stop recruiters from contacting me?
I'm working for a high profile company and have gotten recruitment firms calling and emailing - presumably by blagging switchboard and guessing email addresses - looking to place their (software engineering) candidates in the company through me (a software engineer).
They seem to have my name from LinkedIn or their CV databases and should know that - as a contractor - I have never had hiring authority, but interrupt me anyway in the hope of a referral. I find the interruptions damaging to productivity and would rather they never called. However, I am reasonably likely - as a contractor - to be looking for a role myself through companies like the ones spamming me.
What's the best way to make it clear I do not want them to interrupt me? And is it worth spending time making it clear that I feel they have done something inappropriate?
There is a similar question here, that I have read. In that question one recruiter is calling many times, but that's not my issue. I see a pattern of different people calling and each individual is rude. Another way of phrasing the question might be "how do I deal with random inappropriate calls".
