Your cover letter and resume are typically the first information a potential employer sees about you. Therefore, you want this first introduction to make the best impression possible.
Potential employers are going to spend about 30 seconds reviewing a resume before deciding if the applicant is worth more review, so be sure to make it easy to scan: well organized, concise, and descriptive. Every resume should be accompanied by a cover letter. The cover letter should grab their attention and generate interest by linking your abilities with their needs. Following an interview, you should send a thank you letter. It should be sent by e-mail or snail mail within 2 days following the interview.
The Career Services’ writing tips on cover letters, resumes, and thank you letters are available on the web, along with examples.
