Cover letters are written for many reasons: to inquire about job openings, to request an informational interview, to apply for a position, to follow up after an interview, and to accept a job offer. But do not repeat what you have mentioned in your CV.

- A good cover letter should:
- Demonstrate your writing and professional communication skills.
- Show that you have done your research about the field and the employer.
- Summarize your skills and training relevant to the job.
- Communicate enthusiasm for the position and the employer.
