Extremely unprofessional behavior.
Two weeks ago a recruiter called me and said there was a position open to start the following day. I am currently under contract and I told the recruiter that but he insist that I have a meeting with him. I did so the subsequent week and he asked me to update my resume because there is an open position. I did so before Thanksgiving as promised but now I cannot get a response.
Another incident, received an email from another recruiter with 2 available SQL positions that ended «If you are interested in either of these, shoot me an email.». I responded within 15 minutes, but no response. Tried to follow up two days later and same results.
I find RHT’s recruiting behavior very unprofessional. I know most times its a numbers game and recruiters email as many people as possible but at the very least an acknowledgement that the position is no longer available would be nice.
