Humana Predictive Modeler/Data Mining Scientist interview questions

The interview process was fairly quick in terms of after a call with hiring manager it took like couple of weeks to complete. First round with hiring manager, then with technical person and finally Final rounds. But the worst part waiting for the decision. After my final rounds which happened Online using Montage, I didnt get any reply from them. It has been more than 3 weeks and no reply from them, I mailed them, messaged them even call them, they just dont pay heed to you. This is a disaster,you work so much hard for interview, and these guys don't even feel the need to respond to candidate about the application status.
