What does "What was your experience in the last job?" mean

basically its asking how was it or what did you think about it

What information you gained from your last job.

This would now be an adverb because it’s explaining the action verb. If you were to say “she has taken exercising to a new extremity,” the extremity is explaining the manner the action verb is in, making the most sense. The noun is “she,” the verb is “exercising” so the only option left really is for it to be an adverb.
