I've heard the same IWS.
After talking with about 20 guys and gals who have had interviews with DJ it does seem that the less experienced you are the more likely you will be asked more technical questions( ie High speed flight). When I say less experience I'm talking about pilots with less than 2000-3000 hours and may have little or no turbine time. Anyone with more than that and have been flying RPT turboprops/jets or night freight (both jets and turboprops) seem to get an interview that is more of get to know you. Also if you do miss out the first time, if you get a second interview you can expect the interview to be contain many technical questions.
