Initial emails back and forth to set up group interview took about two weeks. When I showed up at HQ for the group interview, I waited 20 min before the HR person showed up, frazzled, and asked why I had showed up when it was cancelled. I had received no communication that the group interview was cancelled, so I said I could leave and come back another time. She said no, because I was here we could have a brief chat. Jumped in a meeting room and she fired questions at me rapidly, not letting me complete even a brief response before interrupting with the next question. In all, lasted about 15 minutes. I sent a thank you email and didn't hear back for days. When I did get a response, it was vague about rescheduling the group interview, which never happened despite my follow-up.
