Pros
Working on a breakthrough product with top minds in the industry is really inspiring. Very stable and worked through design system as well as a component-driven approach on the front end really make the development faster and pleasant to work. The back end is fast and stable while engineers are very responsive and talented. From my experience what usually takes weeks in an enterprise is done in hours here. I am amazed at how much we've managed to accomplish in one year and it makes me feel like there is nothing impossible.
Cons
It still requires time and excellent hard skills to understand architecture and app state management because the level of complexity of the product area itself is very high. Also, you have to think quickly and always be able to explain your point of view. Nothing is taken for granted. Deadlines are hard that require good time management skills and the ability to prioritize. It indeed creates stress but at the same time allows you to grow and move faster.
