Job interview after rescinded offer

I had a post about a week or two ago, mentioning that my offer has was rescinded from an employer after signing paperwork and going through an on boarding process. I mentioned that I quit my job a month in advance to give proper notice and I screwed myself. I’m currently on a new job hunt and I’m worried about what to say if I get an interview. Any ever been in this spot? Any advice? I’m looking for jobs outside of my field.
