Stellar Labs interview questions

Round one over the phone, round two in their Burlingame office in person. Round two was an interview with someone on the team the role was woking with, and then an interview with the engineers that you would be working with. The first set of folks that interviewed me were great, they were cordial and asked great questions. The engineers that interviewed me were ill prepared for the interview, no prepared questions, everything they asked was off the cuff. At one point I asked the engineers to clarify a question they asked they were very dismissive and rude. In fact, the attitude of the engineers was inappropriate at multiple points during the interview and as I've already stated they were very ill prepared for the interview, it was almost as if they didn't know they were going to interview someone until moments before they were asked to interview me.
