A cover letter that works follows the same shape every time: a hook, evidence, and a close. Skip any one of the three and the letter reads as either forgettable or generic, which is why so many cover letters get skimmed and set aside.
The hook
One or two sentences that name the role and connect you to it immediately. Not "I am writing to apply for," which every hiring manager has read a thousand times, but a specific reason this role and this candidate belong in the same sentence.The evidence
One or two paragraphs that turn your actual experience into proof, not a list of adjectives. Two or three real, specific examples beat five vague claims every time.The close
A short paragraph that reaffirms interest, invites next steps, and gets out of the way. No summary of what you just said.
Everything else, the salutation, the sign off, the length, exists to keep that structure readable in under a minute.
