The 21st Century Resume

Full disclosure- I’m not a millennial.  When I put together my first resume and started looking for a job, “social media” consisted of the group chat “party lines” where you dialed in from the phone connected to your wall, and the only mobile phone I owned was a flip phone that required a special clip to keep it attached to my belt.  We now live in an age where people can apply to jobs on their smartphones, FaceTime/ Skype interviews can be done anywhere, with anyone, no matter the distance; and the savvy professional updates their LinkedIn profile to ensure that they don’t need a resume.  So what does that mean to a person open to new opportunities?  Do you need a resume?
