Very good post PM
Companies like REX recieve hundreds of applications so they want to know the facts fast without having to read too much. They responded to my expression of interest within 3 days so I guess my application was a bit further down the list than PM's
I have actually worked in an unrelated industry where the job was to respond to a generic information email address and it is facinating & daunting looking at the 800 something emails in the inbox. Too much information or waffle is always promptly deleted. There simply is not enough time in the day to read & respond to everything!
