I don't think that's a great example. If Kahneman claimed not to be susceptible, it would have greatly undermined his claims about the universality of these phenomena: many other people would presumably also not be susceptible.
If I remember correctly I took the interviewer's question to mean "now that you're aware of these cognitive biases are you still affected by them?" not "do you experience cognitive biases?". I don't see the first question at odds with the universality claim. The latter would be.
