No NDA on earth prohibits giving a vague idea of what the duties and industry were. You may not be able to say the specific projects you worked on, or maybe even the name of the employer under extreme circumstances, but that would be like MI5 level rare, and those folks aren’t out applying for the jobs you are.
The real trick is having an LLC so you can just point to that and say you were consulting or self-employed during that time. Or have a friend with one.
That would be the um, joke
