Pros

- Great benefits - Good name recognition - Fair compensation

Cons

- Sudden, unexpected early success led to inflated egos and poor governance among company leaders - As a result, the company's culture is a strange mix of entitlement, self-aggrandizement, with some deep-seeded insecurity - From the C level on down, the company says the right things -- from strategy to cultural engineering -- it is about "vision", "diversity" and so on - When it comes down to practice, such as hiring, review or planning, the decisions are often arbitrary, and clownishly contradicting - Yet the enforcement of those decisions is nothing short of authoritarian. PeopleOps operates like a secret police force: some lunch time bantering about the company's direction would be reported, recorded, then came back to haunt you during reviews

Pros

The office is probably the only thing that is a pro

Cons

Everything else. They show that their employees matter through empathy, compassion and so on. Further they preach about these amazing values during the on boarding. But that's where it stops.

Pros

Strong perks, good people, exciting product, great office location

Cons

The company is set up to fail from a data perspective, specifically from leadership decisions - extremely ineffective low-level managers that shouldn't be in a people manager role, a ton of politics, silo'd decision making, blindness to what is really going on from leadership (due to selective communication by certain leaders), and completely shaky infrastructure that sets up any team using data to fail. Directors and VPs changes their vision and perspectives week to week, demand deliverable turnaround within a day with no ahead notice, work is demanded that is unrelated to job roles, over-promising to the exec team and blame their org for not delivering, and failures to self-reflect any mistakes made.
