Via Science interview questions

The interview process was timely and the length was reasonable. However, there was a lack of transparency that I would have expected for a senior role. I went through three rounds of interviews within two weeks, including an 8 p.m. interview with the hiring manager who lived overseas. They asked me to complete a project that took a significant amount of time. I submitted a thoughtful and in-depth strategic plan, and I was essentially asked why I had worked so hard because it was so good. Then, they apologized and informed me that they would have liked me to meet with the C-suites, but they had already extended an offer to someone else the week before (when they had essentially asked me to do free consulting work). I had high expectations for them based on company reviews, but it is evident that they lack a clear hiring strategy and do not value candidate experience.

4 rounds. First screening interview with external HR, then an asynchronous technical interview with SQL and Pandas. Had a bunch of written prompts asking how I would deal with certain situations, asking thoughts on AI, etc. Then technical interview with team to discuss the tech interview. Final round with COO for a culture fit. Was a great experience up until the last interview. COO was a bit rude; she showed up 10 minutes late and seemed very unprepared. Left five minutes in to take a call and really seemed to want me out. Short answers to all my questions.
