Very poor practices by the recruiter who had me schedule a call on her calendar. She gave a 2 ring call 30 minutes before the scheduled time, sent a passive aggressive email implying I had not picked up (I called the number back immediately but it was their generic company welcome message) and then did not respond after I responded courteously that I was indeed available. It ended up taking up an hour of my time of waiting around for her with no response, no follow up, and no apology for HER getting the wrong time. It makes me think it was clearly not a serious interview offer, which is very frustrating given how busy our schedules are. Oh well, bullet dodged and hope this helps someone else save some of their precious time.
