Pros
There are good people and strong engineers here. Some teams still have real talent and professionalism. Unfortunately, they are working in spite of the culture, not because of it.
Cons
Arm, especially Seattle, feels like a company that is actively rotting from the inside. What should have been an opportunity to build a strong office instead looks like a clique-driven expansion dominated by people pulled from the same Amazon circles, bringing the same politics, toxicity, and ego with them. Instead of building a healthy culture, they seem to be rebuilding the worst kind of corporate environment: closed networks, favoritism, status games, and leadership by intimidation rather than competence.
When it starts to look like every new hire is coming from the same division of Amazon, that is not a coincidence anymore. That is a serious hiring and culture problem that nobody seems willing to address. Everyone can see what is happening, but very few people are willing to say it out loud. At least here, it can be said plainly: when a company keeps importing the same people from the same toxic pipeline, it should not be surprised when the same toxic culture takes over.
The culture is miserable. There is very little trust, very little real collaboration, and almost no sense that good work is what matters. People who want to improve things are blocked, worn down, or treated like a problem. Politics and alliances seem to matter more than engineering judgment, integrity, or actual results. It feels less like a serious technology company and more like a collection of inflated egos protecting themselves.
Leadership is one of the biggest reasons this place feels so dysfunctional. There are senior leaders and VPs who have no business being in those roles. Some project no technical credibility whatsoever, yet still make decisions that affect teams, strategy, and careers. Watching people with weak understanding and poor judgment run technical organizations is both embarrassing and destructive. The higher up you look, the harder it is to understand why some of these people are in charge at all.
There is also a deeper identity problem across the company. Arm no longer feels aligned, confident, or well-led. There is visible tension between different parts of the organization, mixed signals about priorities, and no clear sense of vision. Instead of acting like one company with a coherent direction, it often feels like disconnected groups with competing agendas and weak coordination.
Benefits are unimpressive, morale is poor, and the overall culture is corrosive. For a company that should be built on technical excellence, too much of the environment is defined by shallow leadership, internal politics, clique hiring, and people who seem far more interested in power than in building anything worthwhile.
Life is too short to work in a place like this. There are difficult companies, and then there are companies where the dysfunction feels baked into leadership itself. This feels like the latter.
