The best resume tip I can give you is this - Keep it short and sweet! Your resume shouldn’t exceed more than one page. If you are having trouble keeping it to a single page, try removing any experiences that are not relevant to the job you’re applying for. Highlight your strengths and keep it on topic for your shortest and sweetest resume to date.
Also, send your resume as a .PDF file ONLY! No one wants a Word file, or a link to your LinkedIn profile or website. PDF files only. I know PM's who will delete your email immediately if you send anything other that a PDF. Crummy way to not get the gig.
