#HRTech Vegas 2015 is quickly approaching and if you’ve ever wondered what these technical terms mean (Data Developer, ETLTools, Java Script, etc) and how to approach these in a recruiting phone screen or on the #HRTech Expo Hall…here are a few tips!

These tips are designed to help you capture some standard interview questions that can be used during interviews with candidates…and are organized by subject matter area. They’re open-ended questions intended to get the candidate talking about their experience and abilities.  If they can talk through the answers and provide details….that’s a great start and a good sign that they are up for the challenge.
