HR was great to work with — she reached out to me initially, was friendly, and gave me a positive impression of the company. My conversation with the Hiring Manager also went well overall. The process was organized and moved fairly quickly. Made it to the next round with the COO and immediately felt a negative vibe. He came across as uninterested, very straight-faced, and showed little engagement throughout the conversation. While the discussion was decent on the surface, the lack of energy and openness made it difficult to connect and threw me off. A few days later, HR let me know I was rejected.
