The interview was online with multiple participants. Oddly, only 3 out of 4 introduced themselves, and a 5th person joined later, just listening. This made it unclear who everyone was and how deep to go with answers, given the uncertainty about their background knowledge. The conversation just kind of drifted along. We did the usual intros, which felt unnecessary given the info already on the website and profiles. When we asked questions, the answers were often 'not important right now' or 'confidential.' The discussion did touch on helicopters, the technology, and possible tasks, but it wasn't clear what exactly they were looking for, or who they were trying to find. It felt like they were just broadly assessing candidates and would sort them out later, lacking a clear strategy for who they needed. On a personal level, two interviewers were pleasant, as expected, but two others seemed disengaged, with at least one clearly multitasking. It didn't really convey a strong interest in the candidate.
