Pros
Very strong team environment. You get to work with some of the most switched on and engaged colleagues out there. Everyone believes in the mission and are self-motivated to achieve the vision. A strong culture of data science is present so ego's and bravado are mostly left at the door. Everyday i learn something new about data analytics, conversion optimisation, team dynamics and building and optimising products in a billion dollar business. The work is wide and varied and you will be given alot of responsibility. There is no competition between teams. The support network is strong with an emphasis in knowledge sharing and cross pollination between design, product management and engineering. Everyone is there to help you achieve your goals so It's up to you to make things happen. Management is very generous in rewarding standout talent. As a designer, i can ask product managers, engineers and data scientists any question about metrics and they are more than happy to help me be the best at my job. Stop b*tching, start fixing mindset. I love that.
Cons
Because everyone is smart, self-motivated and actively geared towards solving problems fast and efficient, the culture might not suit those who are more suited to slower paced environments.
