What’s it like working as a substitute teacher?

Hi everyone,
I wanted to ask if anyone here has experience working as a substitute ALT for Joytalk. Specifically:

1. What was your day-to-day schedule like? Were you on call, or did you get a schedule in advance?

2. How did the salary and workload compare to regular ALT positions?

3. Were you still able to get company-arranged housing as a sub?

4. Did you eventually get moved into a full-time school placement?

I’d really appreciate any insights, good or bad! Just trying to get a realistic idea of what to expect before making the big move. Thanks in advance 😊
