Pros
Excellent culture. People care about success, not for individuals, but for the company. I'm in product development and everyone cares about the quality of the product. Do we have to make shortcuts to meet customer deadlines? Of course. But that's a conscious choice. The company is filled with learning opportunities and extremely intelligent and experienced people. As a young college graduate, this has been a great community of mentors and colleagues to work with.
Cons
As Workday grows, it's feeling growing pains in its processes and communication channels. How do we ensure speed to market with growing number of dependencies for each product? How do we allow everyone's opinions to be heard without endlessly delaying actual development? These are problems every decently sized company struggle with, and Workday is no exception to them. But everyone is conscious of them and are making an effort to solve these problems. That's all anyone can ask for.
