Final answer:
The statement that a cover letter should be only one or two lines long is false. A cover letter should be half a page to one page in length, and it is a crucial document that introduces your résumé and outlines your suitability for the job.
Step-by-step explanation:
The statement 'When you write a cover letter to answer a job advertisement, make sure that it is no more than one or two lines long' is False. A cover letter should be a concise yet detailed document, generally half a page to one page in length. It serves as an introduction to your résumé and should capture the reader's attention, encouraging them to read your résumé in full. The cover letter should be customized for each position and highlight how your skills and experience meet the specific needs of the job. Remember to integrate keywords from the job ad, maintain white space for readability, and convey your enthusiasm for the position. Always proofread your cover letter and ideally receive feedback from a trusted advisor or friend. Keeping a copy of each cover letter for future reference is also beneficial.
Furthermore, while the cover letter should be brief, it is not as simple as writing one or two lines. It is akin to a 15-second individual advertisement designed to entice a prospective employer. An effective cover letter typically has three to four paragraphs, beginning with an introduction stating the motivation behind the application, followed by a body that details your relevant skills in relation to the job requirements, and concluding with a closing statement that paves the way for an interview.
