When filling out a job application or writing a resume, you need to be as accurate as possible. This is vitally important because the people who read this will likely run a background check to verify what you are telling them in your application and resume.
They will do this to ensure that you will be a good member of their team and be able to do the work they need. Anytime you make a document that others will read, it never hurts to double and sometimes triple-check the page to ensure you have everything correct.
Ensure you have the correct dates and are forthright with what you do and have done. Minor mistakes can be misinterpreted as you being sloppy with the facts. They will worry about what you will do with their data if you can’t get your facts straight.
