Pros
The work itself is literally life-changing for our customers. The people who work here are young, passionate and energetic. The opportunity to travel internationally is incredible. The environment is very entrepreneurial and innovative; no shortage of exciting changes. Everyone is expected to take ownership of their work and act with autonomy. There is no linear career path. If you're a rock star, you can move around and try new things. Very flat environment, not really hierarchical. Everyone is accessible, including c-suite.
Cons
I've seen some leaders of products or divisions do a poor job of change management. Moving fast can be a good thing, but it's really disruptive and demotivating if you don't take into account how to bring the team along with you and involve them in those changes.
