People often demonstrate their suitability for a job by the amount of effort & enthusiasm they invest to get it.
If you put in a minimal amount of effort to get a job, expect a minimal amount of results.
Never underestimate the power of a well written cover letter. Your cover letter is one place where what you say and how you say it can make you to stand out more than applicants who have more experience or better qualifications. Because, it’s easier to train people to do a job than it is to train them to be passionate or enthusiastic about it.
