Learn English – A more formal alternative to “trial by fire”


A group of us were forced to figure out how to perform a task with little to no instructions. The closest phrase I could come up with is "trial by fire", but this is for use in a cover letter for a job. Is there a less colloquial way to express this concept? "Learn on the job" came to mind, but we didn't really have a supervisor to go ask for help.

Consider learn by doing
