How to Write a Call-to-action Paragraph of a Cover Letter
The last paragraph should bring the cover letter to a proper conclusion. It should also STRESS ACTION. Finish strong and quickly. Remind the recruiter what you introduced in the first and second paragraph (how your experience or skills will help the company).
That's the point of a cover letter: a call to action. Inform the recruiter that you'd love to get interviewed too. But be careful – if the last paragraph is too long, you're just rambling and weakening your call to action.
Example: "I look forward to an opportunity to meet with you in person and discuss how my skills could contribute to the company's success."
