Uber

At Uber, you learn new skills beyond coding. For example: proposing a new architecture (mandatory for large features), monitoring (how is my feature performing? did my fix negatively impact any metrics?), experimentation (A/B testing, staged rollout, etc.).

The processes are well-defined: product needs to define the requirements document, engineers define the architecture, the promotion process is rigorous (avoiding cliques), etc.

Engineering culture: a product manager (PM) doesn't set deadlines in isolation. Engineers participate in the conception of deadlines and whether something is feasible to be done in a certain way, etc., and therefore, there's no rush for things to get done.

Salary.

Diverse culture (diversity goals + people working from all over the world).

• The codebase is so extensive that there is a lot of legacy code (Android, for example, still has a lot of Java).
