References. It is assumed that you have references if you have previous employment history. It is not at all necessary to include “references available upon request”, adding this is actually a potential deterrent. Potential employers will ask you for your references later on in the interview process if they see fit. Of course, if references are asked for within the application process, provide them - just not on your resume.
Objective Statement. The objective statement is somewhat antiquated since online applications have evolved. Unless you’re sure that your resume is going directly into the hands of the hiring manager or recruiter, an objective statement is not necessary. If you like the idea of an objective statement, consider adding a professional summary statement instead. While an objective statement explains what you hope to accomplish, a summary statement explains who you are and what you have already accomplished. It also positions you to be desirable to the company, rather than seeming like you are only looking out for what YOU want.
