What if I Get Stumped in an Interview?

Dear Experts, I have an interview coming up with an investment company. After talking with current workers in the industry, I learned the interviewer may ask me questions pertaining to numbers and mathematical problem-solving techniques. If this is the case, then I'm somewhat nervous to be asked a question I simply do not know the answer to almost instantly. Worse than that, maybe not even know the answer to at all. My college-based knowledge is somewhat rusty at the moment. So, if I'm asked a question I don't know the answer to, how do I talk myself out of it? How do I sound like I actually know what I'm talking about, when in fact I may not. Here is how our CAREEREALISM-Approved Experts answered this question on Twitter:Q#483 You're referring to "BSing" your way through an interview question. Not a good plan. Better to admit you don't know. (@beneubanks) Q#483 Sometimes it's not the answer, but the thought process. Take the time to work it through. Best to at least try. (@gradversity) Q#483 Practice as much as possible in advance. With exposure comes composure. If you do get stumped, be honest.
