What he said, the details we're not allowed to disclose due to the confidentiality agreement.
Make sure you have the CI specific paperwork all filled out / ready prior, your recruiter should have access to the PDFs to email you.
Don't leave any part of it blank, even if it doesn't apply, write in either "0" if financial, or "unknown" if you don't know someone's birthday, etc.
They pretty much go over the CI forms and compare to your SF86 to consolidate any differences, they're not there to hound you. In fact, the interviewers are more in the role of preparing the documentation to upload to DOD, where they adjudicate.
They know what/who DACA applicants are so just relax.
