The Bluebird Group interview questions

Completed a screening worksheet that took roughly 2 hours with combined research and development. 45 minute HR interview. 2 hours of panel interview with the team hiring and with a group of employees to go through company culture. Everyone seemed nice, the questions were standard, very easy interview in my opinion. Did not receive any feedback for two weeks. When I inquired about job status, I received the automated rejection email. Seems rude considering all the time they took from me.
