Northrop Grumman interview questions

Got an email saying they had my resume in their database and wanted to schedule an interview. I interviewed with two team leads, which consisted completely of behavioral questions and went very well. Got a call back for a second interview with one of those team leads, plus two others, plus the department head. It was mostly a rehash of the first interview with the only technical question being about Unit Testing. The team lead that interviewed me both times said I did great and they would do my review, which was about 3 weeks ago. Haven't heard from them since.
