A résumé is an important document that employers use to learn about a person's employment history and experience. What information should be included in a résumé to impress a potential employer?

I personally always include:

Why You want the job

Skill lists. You never want to be a one trick pony.

Bloat about your knowledge to the job to which you're applying.

Your educational accomplishments.

And include little about yourself, (not too much bcz, the employer really wont care. they just want someone ready to do the job.)
