Behavioral Technical
A recruiter reached out, and after a quick call, I was invited for an onsite interview. My first impression of the office was that it was small and boring. Someone came in and asked me about my background and previous data science projects for about 15 minutes. Then, another person came in and asked the exact same questions! It felt like I repeated myself four or five times because they didn't want to sit together and ask their questions at the same time, which really felt like a disrespect for my time. It seemed like only their time was important! After all these questions, I waited alone in the room for about 10 minutes, and nobody showed up. When I asked what was happening, they told me my interview was over and I could leave!
