A diligent employee who gets the job done in an efficient way because they want to get home to enjoy the money they just earned?

Ok. If you can explain in a little more detail how you get the job done and what qualifies your assessment of the relative efficiency, then you probably have the basis of a decent cover letter.

Oh come on, 95% of jobs are CRUDs:

- data is in the database

- get data from the database using ORM solution

- pull stuff from Backend (from Frontend), using REST/Graphql

- display it in a nice way using whatever the du-jour styling solution they picked.

This isn't rocket science. Do I really have to make some BS about why I'm "excited" about this company or industry in the cover letter.

Look at the number of applicants at a linked job posting. It's usually high 3 digit numbers, sometimes 4 digits.

Are they really going to read all this flowery cover letters about how you feel about their company.

Respectfully, I disagree.
