Is this normal hiring practice?

I applied for a Project Coordinator role at SoftwareOne and was invited to interview. The first interview never happened due to what was said to be a technical issue. We rescheduled. On the second date, the recruiter postponed again because she was stuck in another meeting and told me she'd send a new invitation. She never did!!!! Instead, I received a rejection email! When I asked what happened, she told me my CV had already been reviewed by the hiring panel before we ever spoke, and they had selected their top three candidates. So my question is: If the hiring decision had already been made, why schedule interviews, ask candidates to rearrange their work twice, and then never send the promised invitation? I'm genuinely curious if this is considered normal or if others have experienced something similar!
