If you've done your research ahead of time, you already know
in general terms the kind of physical work environment this job has
and perhaps you even have some ideas of changes or solutions to some
of their issues if they have any.
Your response then should reflect both your experience
with the specific conditions being discussed
as well as your ability to adjust to any new ones that come up.
Cite specific examples of similar nursery manager jobs

If your experience in the setting is limited, talk about previous
instances where you had to adjust quickly to something new.
