throw in at the deep end

Trial by fire

To throw someone in at the deep end is to put them in a challenging situation with little preparation, like pushing a novice swimmer into the deep part of a pool.

The phrase suggests trial by fire—learning through immediate immersion rather than gradual instruction: My first day, they threw me in at the deep end with a major client presentation.
