In answer to the question, "What's your typical day like?", can I include the evening or perhaps night activities, too?
I had an interview the other day and the interviewer asked me this question and I just answered, "I go to work at 9 and come home at 2." Then it came to me when someone asks you this question, are they interested in your daytime activities (mainly your job) and they're wondering what you do for a living or is it a casual question and you can include anything you mainly do in 24 hours.

According to an elementary textbook The New English File (starting with chapter 3/B daily routine), your day starts when you wake up and ends when you go to bed.
But yes, what people mean in real life depends on the situation. On a job interview I wouldn't include the parts of my day that's not related to work but in a different situation, e.g. a journalist asking it, interpreting when your day starts and ends may depend on you.
So, generally speaking, it does include all 24 hours of the day unless the question is about a specific part of the day or you have reason to interpret it as such.
