Pros
I've been in the industry a long time and it goes without saying that Sift Media is a rare breed: an amazingly supportive and creative environment, staffed by people who REALLY care about what they do - hence pretty low staff turnover. Great collaboration between teams to try to make the sites the best they can be and challenging the status quo is actively encouraged. We also have volunteer groups called Sift Greener looking at reducing the company's environmental impact and Sift Cares looking at our CSR and looking at allow employees to work with charities on company time. Flexible hours...also, two company wide parties per year and life insurance cover - not linked to party antics hopefully ;)
Cons
Personal frustrations include the fact that it's a bit slow getting things through the dev team when I've got clients wanting new formats etc. like yesterday. They are upstaffing and implementing a new Publishing platform, so hopefully this will be quicker in the future. Salary is also probably on the low end of average for the most part
