Cover Letter in "T Format"

Hi Dani
This is not a new idea.  Basically, it shows the screener that you don't know how to communicate effectively and are not a strong writer.  That is even the idea the author uses in presenting who should use this format. 
So unless the posting asks for someone with weak communication and writing skills and does not want to emphasize accomplishments, I would avoid this format.
 

I'd toss this one in the nearest bin.  I need effective communicators and this shows me that a) you are a poor communicator and b) unwilling to get better.
Maybe it would work in some industries but I can't imagine it would get you anything but a low-skill, entry level job.  As I discover, every single day, communication is key.   I have had a direct that will never move beyond entry level because of poor communication skills & an unwillingness to improve.

"T-style cover letters are created using a two-column method showcasing how your specific qualifications match up with the job requirements listed for a position."
 
OK - so forget about the two column formatting thing.  Just throw that out.  But does anybody recognize the idea of showing "how your specific qualifications match up with the job requirements listed"???  Why, that's EXACTLY what Mike and Mark recommend in the "Cover Letter" portion of the Interviewing Series.
 
If I remember correctly, they suggest opening a paragraph with something like: 
"I've read your job description, and my background fits your needs expressly, in the following specific ways..."
 
So yeah - throw out the two column thing.  But don't throw out the core idea of explicitly matching your experience with their needs.
 
A hiring manager once told me there are only two things he looks for in a cover letter:  Did you do the job before?  How well?  His point was that he gets countless submissions from people who think they could do the job if only he'd hire them and give them the chance.  He wants people who've done it before and can prove it.
 
By the way, if you're looking at job descriptions and you use this filter (Did I do it before?  Can I prove it?) you'll stay pretty well focused on those jobs where you'll be a strong candidate!
