Azul Systems interview questions

The recruiter at Azul emailed me and said one of their employees was singing my praises and that he really liked my background, so we setup up an interview. He emailed me less than an hour before the interview and said he needed to reschedule, so I replied that my availability was open and to send over a new invite. Shortly after, I received an automated rejection email. I emailed the talent director so clarify and express my interest in having the chat we had discussed. No response. Very odd, shady and quite frankly unacceptable behavior from a recruiter. 😔
