Match your skills to the job description. Pull out three key requirements from the posting. Show how your experience addresses each one. Use the same keywords the company uses in their listing.
Change your opening line for every application. Your first sentence should mention the company name and role. Avoid phrases like “I am writing to apply.” Jump straight into why you want this specific internship.
Adjust your tone based on company culture. Tech startups appreciate casual confidence. Law firms expect formal professionalism. Research the company’s website and social media to gauge appropriate tone.
