ZOLL Medical Biomedical Engineer interview questions

The job interview process was long, drawn out and unprofessional. The Sydney Aus based HR manager is unprofessional and ineffective to say the least. I called to learn more about the role, I was told they have a candidate and are no longer interested in other candidates, 2 weeks later they called me back and said the job is back on and for me to apply, I did so and even offered to meet up in Sydney when I was there on holiday, I met up with the technical manager, 2 weeks later! They called to invite me to a more formal teams interview, the HR manager organised and was supposed to be in the interview, she turned up in the meeting for 90seconds and said she was busy and had to leave. A week and a half later she finally called to let me know I had the role, we negotiated a salary and I asked for a figure she said she would come back to me, another week and a half passed and I followed up, she now said we have other candidates and the figure I asked for she could not do, I was confused as to why she didn’t come back to me sooner and we could have negotiated. I would have accepted the role. Instead, she went to other candidates, she seemed unhappy at me asking for $5k more, ok well can we discuss this? Instead she said, “we have other candidates you know” ok I get that, I said I would accept the role with the original figure and she said ok I will get back to you, well that was 2 weeks ago and nothing and the role has been re advertised,(so much for other candidates) what a waste of time, I would bother applying to a role in Australasia incompetence is high, I feel the brand is being damaged and things will come crashing down in the near future. Nothing to see here.
