And hungry in the sense of hungry for money, achievements and career, not literally hungry.

I mean some SF folk live in such luxury that they think eating is a nuisance not worth their attention, so they take on subscriptions or all-in-one meal replacements at 10x the cost and 0.1x the flavor of normal food (think Soylent, Juicero, etc).

If your company or colleagues glorify that lifestyle, run away.
