Name your resume "FirstName LastName Resume". No funny names. Avoid over-the-top formatting. Sometimes ATS systems can get confused and jumble your info. You could use tools like kickresume.com to see if your resume passes the ATS test.

Don't waste our time on a cover letter unless you have the name and email of the hiring manager/recruiter, and can send it to them directly. Cover letters should be unique to each position, so don't waste your time unless you are CERTAIN someone will read it.

Remember, your resume is to get you an interview... not to get you a job. Try to read it in 10 seconds and see what you take away from it. That is how long someone will take to decide to read more or to skip to the next one.
