We always recommend starting cover letters from scratch, instead of using a template. This allows you to tailor each cover letter to the specific job so you can show employers why you want to work there and why you’d be a good fit. If you start writing and can’t figure out what to say, it’s probably a sign that this isn’t the right job for you. You have to be able to convince yourself first. Do your qualifications match what’s being asked for in the posting? Does this job sound fun? Is it a company you’re passionate about?
Write honestly, and make it personal. It’s pretty obvious when employers get a recycled cover letter. If you can sound like an actual human, you’re a lot more likely to get a call. And the best way to do that is to open up a fresh email or Word document and start typing.
