Silent executions. Frequent firings. No mention the person was fired. Similar to purges in Stalin era Soviet Union where they removed all record and even airbrushed people out of photos. ICs get fired. Managers and directors get fired. There hasn't been a VP firing in a while.
Any technical interest is eclipsed by the lack of freedom to influence the direction of the organization, product, or codebase. Some thrive, but most have their wings clipped. You'll probably be the latter.
Personality cult around their founder. If you work in the sphere of influence of their founder a reality distortion field will set in. The laws of organizational physics won't apply. You will be micromanaged like never before and you'll be lucky to survive a year or two. Best to avoid those areas.
Some competent, core people but huge swathes of deadwood. Similar to how they backend load quality (inadequate investment during product development, huge release support costs), hiring strangely follows this backend load model. The bar to get hired is often quite low. If later it's discovered that you weren't what they really wanted then no problem, you'll just get axed. Not a good way to run things.
