Just No
Can we all agree that “drinking from a fire hose” is a terrible metaphor for the feeling of starting a new job? It’s overused, cliched, and kinda gross.
What I find most funny is that it’s usually stated as a humble brag about the amount of information you can ingest in short order, or to indicate that your new company is some kind of special unicorn doing work so incredibly complex that it overwhelms all who dare join it.
Reality is that the feeling of being overwhelmed in a new role is totally normal, even if the work is banal or the company is pedestrian. Sure, it takes time, but don’t make it sound harder than it is.
