      Pros

      - Cutting-edge work in quantum computing and AI. - Talented coworkers who are motivated by the science and innovation. - Equity grants remain a significant upside if the company executes well.

      Cons

      - Career growth and recognition continue to be major pain points. Advancement beyond certain levels feels unnecessarily difficult, often more about navigating politics than merit. - Communication from leadership can be inconsistent, leaving employees uncertain about expectations and direction. - Resource constraints and shifting priorities create a chaotic work environment, leading to inefficiency, burnout, and difficulty planning effectively. - Some signals from leadership suggest admiration for high-turnover, high-burnout models, raising concerns about the company’s long-term culture.
