Did you work there? The promo process, especially at the higher levels, does reward ability-to-explain-and-contextualize over pure technical ability, but my opinion is that senior engineers need more of the former than the latter anyways. Deeply understanding your product and what is necessary to make it better can be more important than the ability to pump out algorithms and models.

Yeah I used to work there. Not sure about the higher levels but the incentives in the L3-L5 range were very messed up.
