I recently got back from MCPHS and I got my acceptance letter a week later. The interview was really laid back and stress free. The students on campus and the staff were really kind and friendly. As for the essay question, they had a list of questions you can choose from and write a paragraph about the topic. I can't remember the questions, but its nothing to be worried about. They just want to see if you can write a sentence with punctuation and thats what they told me on the interview.
