If one applies to one job then the chances are that that person won’t get that job. I am applying for ACA training contracts. I guarantee that no matter how custom made I make my cover letter, I won’t get a position if I send it to only one company. I have got a list of 86 employers that have vacancies. 86 might give me a 5% chance when compared with just 1 application. However I can’t spend 2 hours on each cover letter for 86 employers – it’s simply not possible. But trust me, I WANT their jobs and I have commitment.
When human resources professionals collect resumes for a job opening, they generally expect cover letters to come with those resumes. A cover letter gives you--the job applicant--the opportunity to introduce yourself and briefly explain why you think your resume is a good match for the available position. Since most of your experience and education will be listed on your resume, you can use the cover letter to explain why you want to work for a particular company, or what makes you stand out from other applicants. Write a cover letter to human resources that is personal, relevant, professional and free from grammatical or spelling errors.
