Cover letters can be difficult to write and the most annoying part of any job search.
Most employers probably toss them in the trash anyway without ever looking at them, so they’re not even necessary anymore in today’s job search, right?
Not so much. If your goal is to not make it to the interview round, then no, you definitely do not need a cover letter to accompany your resume.
As a hiring manager, I evaluate every cover letter I receive to see if a candidate is serious about pursuing the position I need to fill. A good cover letter can tell me something about you that your resume does not: who you are and why you are the best candidate for the job.
So, yes, employers definitely do read your cover letter. In fact, it weighs more heavily in the hiring process than you might have thought.
