Yeah it depends on the reason for leaving. I know in the company I work for your termination reason shows if you can be rehired or not in the future. If it says you can't be rehired, they won't even call you for an interview. That status stays on your record forever. Now if it is a grace period type thing where you left on good terms, then that would be up to the company. My company has no such period. You could leave tomorrow and they could rehire you 2 days later. In fact all companies I have worked for were like this. Now theme parks may be different as it was stated Disney seems to not rehire within 6 months. But I imagine it has to do with the position also.
