Like everyone else, I defiantely think you should go through recruitment and ask the chapters how things work with different schedules.
Time constraints were also a concern of mine when I was going through recruitment, and I asked about it, and now I am really glad I did! When I asked about it, they told me how their chapter works -- like for example, on Monday nights we had our chapter meeting, and after regular chapter meeting we had our Alpha meeting. This was done so that the Alphas (new members) wouldn't have to take 2 nights off of work for meetings (for those that worked), and also so we wouldn't have to schedule study time around meetings twice a week.
Don't be afraid to ask questions
The sisters will all be more than glad to answer them for you!
