Vantaggi
The vision of the company is clear and the products are very customer-centric. The company is established in a very interesting sector with many challenges to solve at big scale. The engineering department is a small team of talented and friendly peers. There are no big egos nor rock stars, just good professionals doing their best for the products of the company. Because the size of the team, you end up working on all the layers of the products and everyone's work has a big impact overall. Also, the stack used is cutting edge and ever evolving, which is rare given the size of the team.
Svantaggi
The company lacks some fancy perks offered by others (e.g. restaurant and transport tickets), but it compensates this fact by offering fair salaries. Another point is the office. Although it is ok overall and has good location, it should be way nicer considering that it is for a successful company a not a startup (actually many startups have stunning offices, but that's another story!)
