The question is, how do you respond when you don't know the answer to a question? So if I don't know the answer to a question, nobody knows everything. So what I would do is, I would probably ask my superior and give some advice to somebody with more experience and I would try and move from there and from that moment, I would probably know from the situation. That's how you know you get more knowledge or experience. So if I don't know something, I ask questions to my superior or someone who has better experience to it.
