congrats on the interviews! i applied to lasalle's psy.d 2 years ago, interviewed and got in, but ultimately decided to go for an MA at columbia's teachers college and re-try for a phd this year (i really don't want to pay for school, haha)
i had some tidbits for you guys interviewing - i remember it was the only place i interviewed that asked you to write essays while you were waiting (during the "down time"). and you had like a half hour or 45 mins. they weren't intense questions, and i don't know how much they weighed it in their decision, but it's something to be prepared for! and as far as what the questions were, don't bother asking because i completely forgot (must have blocked it out of my memory!). good luck to you all
