Two stages. Hiring manager reached out to schedule an interview. He was friendly during the interview and it was enjoyable. Then came the panel interview. First interview was a case study with a PM. He seemed bored, complete opposite from hiring manager. His question was how I'd name a train line. I asked about the business objective. He laughed then said you tell me. I tried to ask more clarifying questions, he basically told me to make all the answers up myself, not answering any of them. Okay, so I attempt to answer this broad question without constraints.. It inevitably gets messy. Then he laughs multiple times while I walk him through my solution. When I'd suggest something he'd smile, chuckle, etc in a condescending way. Overall he just seemed totally uninterested in this interview and rude. I felt like I was set up to fail. The other two interviews with marketing and engineering were for fit and those were pleasant. A week later recruiter calls me with feedback, everything went well except the case study so I wasn't chosen. I wasn't surprised. Perhaps the interviewer already had another candidate in mind, either way that was not a great way to interview candidates.
