You do need a resume, and it has to be flawless. But its details matter less than ever if you are looking for work right now. Your resume today is a reminder for the person you interview with about things they already know, because they likely already know you through Facebook, Twitter, LinkedIn, friends of friends or professional circles. Do not imagine for a minute that sending an unsolicited resume to a company is going to get you a job. It might, but there are other ways, and they are faster and more effective.
