Called for in-person interview. Asked to bring a sample lecture. It was time consuming to prepare and travel to campus physically. Later, someone from the scheduling team called me to ask me if about giving me courses to teach. At this point, I hadn't heard from HR, there was no discussion of pay. Still, I gave my availability and then was ghosted. I sent a couple of follow-up emails, but no response. I was asked about my salary expectation at the interview, even though they didn't share their offer salary. Extremely sketchy and unprofessional management.
