Applied at large aerospace company for technical role

I had an onsite interview today with a large aerospace company for a technical role. I was originally scheduled for five one-on-one interviews, and I was really looking forward to it. However, after completing the third interview, I was told during a break that the hiring managers needed to wrap things up, and they canceled the last two interviews. It was frustrating because I had traveled a long distance for this opportunity, and I didn't receive a clear explanation for the sudden change. The recruiter mentioned that it ‘may not mean anything bad’ and that I should expect an update soon. I'm left wondering if this is a common occurrence in large companies or if it indicates a decision has already been made, whether positive or negative. Has anyone else experienced something similar?
