I was allowed to talk during the interview, which was great. Consequently, I wasn't asked very many questions - especially during the first interview where I spoke with someone more closely aligned to my skillset.
The second interviewer, whose task was to evaluate my understanding of threat behaviors, initiated probably one of the the more important discussions which was in regards to shell scripts. What are they, how do attackers use them, how can you tell if they've done something, etc.
