Temple's essay is no big deal. It'll be some topic that has no right answer. I think mine was "How do you tackle a big responsiblility" or something like that. Just be yourself, and write what comes naturally.
One tip when interviewing at temple, make sure you remember the names of everyone there (especially the students you meet). Also, if you really like the school, email them after and tell them how much you liked it and why. Trust me, they will appreciate that.
