According to Celeste Joy Diaz, a recruiting manager at Amazon, your résumé is a recruiter's first impression of you during the job search. Diaz said not explaining your job accomplishments clearly is the primary way to alienate recruiters from the beginning. Diaz recommends using hard numbers to demonstrate how you have succeeded in previous roles. Diaz told Business Insider "Titles are great, but we want to understand what was the project you owned, what was the scope of a project, and what did you accomplish,"
