Pros

Criteo is a fine place to work, I'm fairly confident it is the best tech company to work for in France. Criteo's culture is very performance driven, and engineers apply all the best practices in the field. Criteo also has a lot data to work with, which is a data scientist and machine learning practitioner's dream. Technologies used are fairly top notch, Criteo has its own data centers, its own SRE and Infra departments, and many tools to ease the development and deployment processes that rival those of cloud platforms.

Cons

The company is somewhat stuck in a limbo between a small startup and a big tech company. It's engineering department is concentrated in France (since it's SF branch has closed), which makes it rather close-minded and less open to the adoption of new and state-of-the-art technologies. The development processes are fairly slow moving, which have made the company fail to diversify its product portfolio in recent years (although it's going a bit better lately). There are several structural inefficiencies, starting from a very big pile of technical debt, that you need to circumvent and adapt to in order to make new products and produce value (it takes effort but it's possible).

Pros

Smart, hardworking people at the individual contributor level (many of whom are now gone). Little micro-managing, but that’s because everyone’s bandwidth is near 0

Cons

Post–new CEO, the company has descended into complete chaos. There is no transparency around decisions that impact teams and roles. There have been consistent strategy, personnel, and supplier changes with no explanation, accountability, or follow-through. Cons, continued: Employee input and performance do not matter. Decisions feel driven by appeasing BoD and optics rather than results, input and reality. The culture has become a corporate hellscape of: Endless reorganizations with no clear rationale, including layoffs with no reasoning Vague all-hands meetings that avoid real issues, even when directly asked A massive disconnect between the C-suite and day-to-day reality Eroded trust and growing position insecurity Middle managers incentivized to prioritize managing up & executive optics over team advocacy “Return to Office” policy put in place when promised a “Work from Anywhere” position, where the RTO policy differs across employees’ location Little to no growth opportunities despite high performance Under-market average compensation that was justified by locale, “Work from Anywhere”, and flexibility — which was recently rolled back A clear favoritism to those that “talk the talk” vs “performance with numbers”
