A biotechnology internship cover letter is a one-page document that accompanies your resume and explains why you’re a strong candidate for a specific internship. Unlike a generic letter, it should be tailored to the company, research area, and position.
In biotechnology, employers look for candidates who demonstrate both technical knowledge and scientific curiosity. Your cover letter should show how your academic background, lab experience, and personal motivation align with the organization’s goals.
