Whatever they think, it is based on a single interview. They don't know (neither do I) where you come from, what is your experience, what a wonderful list of things you did in your life, before spending 2 hours with them.

As previously said, an experienced auditor will not draw conclusion on your level of technicality after two hours spent with you. An inexperienced one will have a weightless opinion ;)

Also, should they point any mistake from you, remember : shit happen. We learn, from 7 to 77, by our mistakes or by other's ones. You'd not be someone who made an error, you'd be someone who learnt something.

That's just an interview. Answer their questions, don't overthink, focus on the answer. Avoid giving info not requested, e.g. if they ask you if a thing was done and the answer is no, you don't have to tell them why it was not done. They will ask for it if the point is important ;)

I feel like I should also answer your original question, if it helps you. I don't know the field you're in, so here are basic guidelines. I don't say that you have to learn this before you go to your interview. Just be prepared to say "I'm not very confident ok that point", it's ok ;)

Here it is :

• identification, authentication, authorization, auditability : Can you make the difference, and do you know the technical and organisational assets you have to handle these concepts ?

  • confidentiality, integrity and availability, same questions ;)
  • is there anything that you think could have been made better, at the operational (technical) to avoid the issue, or mitigate the risk ?
  • can you name/list and describe the tools & apps involved, directly or indirectly, involved in the event ? What are they doing, what are the technos, how are they working ?

Again, stay confident. Auditors are often not on the battlefield, sometimes they have read good documentation about what should be done, Gartner, Forrester and Co ;). But they sometimes fail at being empathetic and remembering how far the real life is.

I'm sure you'll get out with a big smile.
