CARS24 Australia interview questions

Had three interviews in three days (phone, first stage (which they conducted in their car), and second stage). Spent almost three hours in total interviewing. What started as them extremely keen to fast track my application to then be ghosted. I was told in the first stage that after the second stage it would progress to references however in the second stage I was told there would be a third interview but they didn’t know who it would be when I asked (they threw some names around but said they weren’t too sure). Didn't hear back from them after my second stage interview, followed up, withdrew my application, and still no correspondence to this day, 3 weeks later. I was told a Senior HR Associate (Advisor) would be a more suitable title based on my experience and I was even told they got “approval” for an extra $5k from the $75-80k base salary being offered. They spoke enthusiastically about how “competitive” the salary was for the role compared to market and tried to justify that the annual bonus, phone and study allowance “bump it up”.
