Sounds like an effective filter to me. Where I work, this would be the first part of one of the interviews, with the second part being something more like "Given a list of calendar appointments, what is the maximum number which can be attended without conflicts?"

[bryanrasmussen]

don't you need a little bit more info about that list of calendar appointments? like at least an assumed time length?

(assuming the list happens on the same day)?

Yeah I was thinking each appointment had a start time and end time.
