I have worked a lot with DevOps people in general. The best ones had following : - Amazing shell scripting and linux command weaponry. - They keep up with the latest tools like docker, new relic or puppet - They over monitor stuff using tools like ganglia, zabbix, logstash(splunk), datadog, etc. - They have flexible mindset (to do quick hacks) to buy time for dev team. - They have flexible time schedule. (act to an alert at 3 AM) - They consider themselves to be part of Dev team, admin team, DB team and are clear in communicating their ideas.

That means a "DevOps" should have all the experience to work in different teams. For example he may start his career as dev then move to some sys admin jobs. Meanwhile after working for couple of years with both Dev and sys admin team he could call himself "DevOps".
