A resume with a cover letter carries more weight than one without. The cover letter demonstrates your interest in the position and highlights your work experience and commitment to the specific company and role. If you have the opportunity, it's worth asking the recruiter about the difference between submitting a proposal with a cover letter and one without. They will likely emphasize the importance of a cover letter. You can save both time and money by allowing skilled writers to provide you with a cover letter that showcases your professionalism, skills, and experience, as it will demonstrate to the recruiter that you are a serious candidate. Otherwise, submitting a proposal without a cover letter may result in companies not taking your application seriously, leading to wasted time.
