It depends on how many applicants there were and how far they got.
It's not easy sending personalised feedback to lots of people, it takes time that H.R depts these days just don't have.
Anyway - Why would you rate an ops department based on what kind of charts they use? Paper has served and continues to serve airlines the world over without any problems...that's a pretty strange criteria for measuring employee satisfaction, no?
Try not to take it personally.
