Great People, Poor Leadership

Pros

• Competitive benefits. • Hardworking non-manager employees. • Excellent facilities teams and modern offices (some with free lunch). • Global footprint offers diverse, talented colleagues. • Still growing, though not fast enough for investors.

Cons

• Culture declined sharply, with frequent reorgs, poor communication, and no clear direction. • Executive leadership is a revolving door and makes reactive decisions without proper planning (e.g., rushing out a copycat hybrid policy after Amazon’s RTO announcement, without ensuring offices had enough desks). • Low morale driven by shifting priorities and lack of recognition. • Toxic managers who take credit, shift blame, publicly humiliate reports, and are either overly controlling or completely disengaged. • Career development is virtually nonexistent. Goals are vague, constantly shifting, or contradictory. Meanwhile, higher-level roles appear with low requirements and are given to cheaper external hires while qualified internal employees are sidelined or discouraged from applying. • Raises and bonuses are underwhelming. One profitable quarter, bonuses were cut to less than half of target, followed by "We Appreciate You" cookies from HR - a tone-deaf gesture that highlighted the disconnect. • Hybrid policy has a clear double standard - most leaders work remotely, while others are held to an overly broad “commuting distance” rule. • Departments operate in silos with limited cross-functional collaboration.

Over Promise, Under Deliver

Pros

The people you work with are smart and always willing to help. There wasn't a peer that wouldn't go out of their way to offer assistance or make some time to hop on a quick huddle.

Cons

Lots of over promising, saying things will get better and more efficient, that they are hiring more people to lighten the workload. In reality you will have ever shifting priorities, under delivering on their promises or just completely unfulfilled, and unrealistic goals that only a select few achieve because they sacrifice their work-life balance.
