Salesforce Software Developer interview questions

Incredibly unprofessional across the board. I took a recruiter call, but she couldn't give me any specifics of the role nor the tech stack. Easily the most incompetent recruiter I've ever spoken to. She couldn't answer any questions whatsoever. If I asked anything, she launched into memorized gibberish. She claimed the role was perhaps confidential? But it would all be resolved by the hiring manager... Who never called me. Recruiting sent me a confirmation email, and then no response after that. Not sure how you can ever hire anyone with a process like this.
