For initial access i talked about drive by downloads/watering hole techniques and methods to mitigate and detect it. After a while the other interviewer asks me - tell me a way an attacker from the outside would get into an organization?? well, drive by downloads is one such technique. I also mentioned valid accounts and spear phishing.
Also when i mentioned drive-by downloads the interviewer mentioned that this technique is after an attacker has access to the system (LOL *BANGS MY HEAD TO THE WALL*). This technique is USED for initial compromise. How are these people even security professionals?
