Ask HN: Is promotion harder on less visible teams?

Hi HN,

Lets say there's a hypothetical situation between and work on a low-visibility team and a very high-visibility team, ads for example. Which one is easier to get promoted on?

My question is basically how are the promo committees set up? On the user-facing team, the impact is much larger, actually generating revenue for the company, but the work is far more challenging. Paradoxically, could this result in a situation where it's harder to get promoted on this team? One could imagine on a less visible team the launch process is much kinder, resulting in a big fish gets promoted in a small pond kind of situation. Or do large companies take this into account when doing promotions?

Any insight into this would be super helpful. Thanks!
