While not every job requires a cover letter, including one is a great way of adding to the "story' told by your résumé. If you choose to include one, your cover letter should not just restate your résumé, but help the recruiter understand why you’re interested in the role or career path, and what makes you distinct. Tell a brief story or share a unique fact as appropriate – we like getting to know you!
You may address your cover letter to “To whom it may concern,” “Recruiter,” or “Hiring Leader” as there will be many people reviewing applications for our internships. It is also not necessary to include a physical address on the cover letter – a city and state are enough.
Don’t be afraid to ask for help. Your school’s career center should be able to assist in polishing your résumé so that it is practically perfect in every way!
