Please tell me this is a troll. I mean, I've seen some pretty incompetent people doing jobs they're not cut out for before, but I really want to believe this level of incompetence can't actually find jobs.
Back then, I used to believe that people know what they are doing, but since I've lived long enough know, maybe not.
You gotta be careful, people like that will come to personality attack when push come to shove. When facts are against them, it is now time to yell.
The sort of interview that this guy would do well in is a poorly-conducted one. A simple question like "what does it mean to hash a password and why would one do that?" or "what is PCI?" would expose his incompetence.
