Why a Cover Letter Matters for Engineers

Many engineers underestimate the importance of a cover letter, assuming that technical skills alone will secure the job. However, hiring managers often use cover letters to assess communication skills, cultural fit, and motivation. A well-written cover letter can highlight achievements that may not be obvious in your resume.

For example, your resume may list “developed automation tools,” but your cover letter can explain how those tools reduced operational costs by 30%. This storytelling element adds depth and credibility.
