Hey! I actually enjoyed the interview day! GWU did a great job in making it a day where you can get to know the school, its students, and staff just as much as they get to know you. We had a group interview to begin with (about 4-5 people in each group) where a faculty member led discussions and questions involving PT and the workplace (so knowing a little about how PTs actually operate in the field will be helpful). The day ended with a one-on-one interview which was also very chill. All in all, it was my favorite interview to date and I am anxiously awaiting to hear back from them!
Good luck on your interview!
