They lay people off to often and without notice

Oncall is extremely unhealthy—expect frequent pages in the small hours of the morning to attend to legacy systems. Tech stack is outdated and tightly coupled with significant friction around adopting modern frameworks or technologies (at least in service teams). Extensive meeting overhead, particularly six-pager reading sessions that consume multiple hours (sometimes for no good reason). Leadership Principles are often used to stifle productive debate rather than enable it. Stack-ranking performance culture creates a competitive rather than collaborative environment. Promotion process emphasizes documentation and self-promotion as much as technical contributions. This leads to senior (or aspiring senior) roles finding ways to publicly "meddle", simply to show "impact". Re-orgs and redundancies. Constant restructuring, focus shifting, and all the meetings, stress, and uncertainty that come with it.
