I am applying to research and design engineering positions in the medical device industry and have noticed that all applications have an option to upload a cover letter but they are never required. I have a general purpose cover letter that I drafted back in college and am not sure if I should upload a version of it with each of my applications. The document outlines a few of my prior work accomplishments, but all of the content is covered and summarized in my resume. The only unique bit of information is a declaration of what my near future plans are in terms of career development (1-3 years time frame). In a technical skill driven industry, I am not certain that a cover letter will provide any additional information on my qualifications that are applicable to the position that I am applying for.
Question: Does adding a cover letter that has been slightly modified to fit each individual company add any value to my application?
