Go for work but dont go if you want to climb up soon - Manager bei Rivian: Mitarbeiterbewertung

Startup, people care about the work being done.

Upward mobility is unclear, and competitive.

Employees share a strong sense of commitment to the mission and are generally high quality. The products are not perfect, but they are excellent and improving.

Decision making processes are immature and/or non-existent. Decisions are made top-down, often based on long standing personal networks, not merit and analysis. Organizational politics and doing things based on how they will appear, not how they impact the business, are prevalent.
