Pros & Cons
OpenAI

- Internal politics and rapid org changes as the company scales
Writer
- Real AI engineering with proprietary LLMs — not just wrapping OpenAI APIs
- Strong enterprise traction and visionary product direction
- Intense work culture with very high expectations and limited work-life balance
- Growing management layers creating organizational friction
Bottom Line
OpenAI
High-intensity, mission-driven culture with world-class colleagues and top-tier comp — but expect long hours, rapid org changes, and internal politics as the company scales.
