Miele Manager interview questions

Applied online, process took a few weeks. First HR set up an interview with the hiring manager. Had that interview, felt it went great but had some HR related questions, so I had to get in touch with their HR. They set me up for a 2nd interview with someone I assume would have worked closely with, that too went well and they moved me on to the final round. Prior to the final round, the hiring manager wanted to interview me again. Went on to the final round with their CFO. Felt even better about the role and was looking forward to hearing back. It's been 3 months without any info or feedback. I reached out but no response. Completely ghosted and disrespected.
