Alternate point of view here from someone who has done a lot of hiring. I find this advice really odd because it's a struggle to find someone who can actually do the job and you are always desperate for technical talent. I have never seen any emphasis placed on cover letters or resumes when screening candidates. Instead it's usually things like online coding tests and phone interviews. I can see this being more important for executive/sales/marketing positions that require soft skills that aren't easily gauged.
