Autozen interview questions

I was approached by Autozen because I have experience in a very similar niche industry. What was framed as a 'chat' about a 'potential opportunity' quickly turned into a one way fact finding mission on their end. I was asked about the inner workings of my last company. Processes, systems etc. Hardly anything of substance was asked about me personally. I got the typical interview questions (describe a time when...) without a real job description in front of me. They even had the gall to ask my salary expectations. Uhh for what job? It was expressed early in the call they didn't know what they were hiring for yet. I countered by asking what the hiring budget was. They danced around this, then asked straight up what I used to make in my last role. When asking for feedback later in the week, I was ghosted. Seems like they got the info they needed out of me, and that was that. Lesson learned not to disclose as much as I did without a legitimate JD next time. Based on other reviews, looks like a bullet was dodged here. Beware.
