SpaceX manages to make things work despite rampant burnout induced quitting so its not impossible. Shorts used to make fun of Tesla and how any experience walks out the door with all the turnover but they seem to have a handle on things as well (less so than SpaceX).
If management is checked out I agree that it is less likely to turn out good which is what I think happened here.
Alot of bright, energetic people out of school sign up because they are doing something unique and cool they truly have a passion for it. So even though the reviews of the place are terrible they will always have a line of talent at their door (atleast until they have more competition). If you are attracting the top tier talent every year, that can solve alot of problems, even if they aren't that experienced.
That being said you are still leaving yourself wide open for failures. Engineering failures often involve people being overworked, not having adequate experience, and working in areas with high churn. See Boeing as an example.
