They really weren't bad at all and I wouldn't worry about them. The writing activity was pretty straightforward and nothing that's meant to trip you up. Also there's plenty of time to write a thorough response. The group/community interview was also super chill. It kind of depends on your interviewer, but mine was really nice and didn't ask any really challenging questions. It was just me and one other applicant and felt more like a student interview as far as stress levels go (so very low). Definitely prepare, but don't stress about it! Everybody was so nice, this was definitely my favorite interview day.
