<human>: While I look for a full-time job that pertains to my degree, I figured that I'd apply for some part-time positions in retail, just so I'd have a temporary source of income. 

(In this case I was applying online to CVS Pharmacy)

Right at the beginning of the online application it asks for an uploaded resume, and then says:

"Cover Letter Optional" 

Feeling ambitious..I decide to write a cover letter (I've been out of college for almost three months and finally feel a sense of urgency to land any sort of job). I'm inexperienced at writing cover letters, so I draft mine based on a sample one. 

"Mention the position you are applying for, why you think you'd fit well at that company, and why you like this company"

Somewhere along the way I completely forgot that I was applying to CVS, and instead I put Walgreens, their competitor. 

After I submitted the final application they required that you "try out" for the job via an online qualifier program. I clicked the link to the module and then realized that it was for CVS and not Walgreens. Fuck.

Not so much a significant error, but embarrassing nonetheless. This was one of the few places where I was almost 100% certain that I'd get the job.

Provide a brief overview of the text.
