Thank you for taking the time to clarify those requirements that I did not satisfy — this will help me when applying for other roles, and I appreciate the feedback.
As a writer, I'd like to offer you some feedback also. Your note below that the client is "seeking candidates with construction and heavy engineering experience" has a very different meaning from what was posted in the job advertisement: "If you have previously been exposed to documents relating to engineering this will be advantageous." The former implies a strict constraint, whereas the latter implies that some flexibility exists.
TI don't think it quite qualifies as a rant, because I was attempting to give them some useful feedback. I even resisted the urge to explicitly point out that their lack of attention to detail in the listing meant that I had wasted my time applying and the recruiter had wasted his/her time reading my application.
I haven't received another response from that recruiter.
He/she has confused me somewhat, because my prior experience has been that recruiters tend to overstate requirements. For example, I was recently interviewed for a role requiring an "extremely capable and experienced Technical Writer" (which I clearly am not).
