Where the channels break
Channels can share facts and still weaken the story.
When the resume, LinkedIn profile, and cover letter do not work together, the problem is usually in the relationship between them. Each one may mention similar facts, but they are not building toward the same conclusion.
Everything sounds aligned because the same message is repeated everywhere. But the resume, LinkedIn profile, and cover letter should not all do the same job. When each piece repeats the same claims, the reader learns nothing new from the full set.
