Hi, when I do not know the answer to a question, of course, depending on who I'm talking to, depending on the situation, but it will vary of my entire response. But I will always start off by being honest, because I want to make sure that the person is getting the full correct details. And so I'm always very honest. And I might say that I am so sorry, I do not know the complete details of complete details or answer to your question, but I can surely get back to you as soon as possible after I talk to my supervisor. Or I can say, let me look into that I do not know all the details. And I will surely get back to you. I would just want to reassure the person that I will get back to them with their full answer depending on whatever they may be asking. And I will also always start with being honest, and saying that I can find out the answer to their problem, or their question. And I may have to just ask another person and then I will surely get back to them. Or if I need to refer them to another person, I can also do that. But I would just start off by being honest, saying I apologize, I do not know the full extent or details of your answer, and that I will surely get back to you as soon as possible to reassure them that I do believe that their question is very important and valuable. And I just want to make sure that I have all the details before I share anything.
