Just started looking at job listings and this is common (actual quotes): "Ideally someone who lives and breathes code", "does development side work", "practices new technologies at home", "likes to code all day everyday", "attend and present at meetups", "commits to open source"
On top of that a majority of listings have something like this one: "Experience with many of the following: Eclipse, Pig, Hive, SVN, Git, JBoss, WebSphere, WebLogic, Tomcat, Apache, Linux, SBT, JUnit, Maven, ANT, Hudson/Jenkins, JMeter, JProfiler, JIRA, Bugzilla, Agile, Java, Android, Scala, Groovy, Hadoop, Apache Spark, Akka, J2EE, EJB3, JPA, Hibernate, Struts2, Play Framework, Spray Framework, Grails, Spring, XML, JSON, XStream, Proficient in HTML, CSS and JavaScript"
