I did rotation based IT for awhile and the questions that people ask are good but the #1 in my book is: - Will you get any form of compensation if you have to work after hours? Where I worked - that was a no. You were paid industry minimum and when you were on call - you were expected to be alert/on call 24/7 AND come in and do your normal 8+ hour shift. Now - I don't mean a 1-1 level of compensation but at least be flexible especially if you were on call. The calls themselves weren't usually bad - but if you have to come in on a weekend anything you planned on over the weekend is now shot and that can be extremely stressful.
