I feel your pain and also agree with Shelley O from P. Fla.
I have spent extensive time crafting, recrafting, and tailoring my curriculum vitae and cover letter for advertised positions to no avail.
It is extremely frustrating to invest this amount of time and effort in response to job postings that seemingly mirror your qualifications.
As an HR professional who has been on the other side of this table, I can only commit myself to ensuring that once I regain employment in my field, I do not allow this to happen to prospective candidates.
In Regard to Shelley O's response, I have to say that your posted comments do not reflect the professional, polished, communication skills employers expect from candidates.
This communication is the first opportunity to present yourself. It should equally reflect your communication skills along with your education, background and experience.
I too wish you and all the others sharing this commiserate experience well...
