alt Hacker NewsI've contracted at several big tech companies and that other commenter is making stuff up. My experience was similar to yours, the engineers were very productive on impactful projects. I'm sure there is some dead weight in every company, but it's the exception not the norm.
It sounds like you have financial incentives motivating your desire to shape opinions on this issue. I already exited big tech so I'm able to be candid. But don't worry, giant companies aren't going to stop your gravy train, they already know you're not highly "productive" and "impactful." That's the point.
If you were actually important to the organization it would be a terrible mismanagement of the company. A well-run big org is designed such that workers are replaceable cogs in generalized salary bands, that's what makes the machine durable.
It's very easy to think you're "productive" and "busy" when your days are filled with meetings and trying to placate various groups of stakeholders. But if you look at your actual work output after a year in big tech, it's fundamentally low impact, and it's that way by design.
