One effect that parallelism has on a written work is that it emphasizes ideas.
Explanation: Parallelism is a literary device that is used in many literary genres, even though is mainly used in poetry.
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.)
Contempt is the only one that makes sense! :) I hope I helped!
