Pros
I have been at Rivian over 2 years and I would rate it 5 stars until last year and 3 stars now. Lots of passionate, dedicated people driven by mission - It can be a fun place to work if you are in the right team! Huge opportunity to learn and expand your understanding beyond your core area of expertise. Very dynamic environment - lots of decisions to be made. If you are willing to take ownership there is huge opportunity to grow. Culture - The company culture was great and there are still individuals working hard to keep it alive!
Kontras
Culture - With the company growing so rapidly the bar on hiring has gone down. This is especially true for leadership. Newly hired leaders do not respect the company culture that existed, and all new hires they are bringing in are similar. Lack of communication - With so many work locations there is no good mechanism to provide progress updates at a company level. Very few company-wide or department meetings or channels to share information so as an employee you can feel left in the dark.
