Interviewers need to be aware of any potential conflicts of interest when working with money, and it is very important to be candid with the interviewer about any relationships you have with people who work in the industry. Think through your friends, immediate family, and extended family. Does any of them work for this company? If so, tell the interviewer the person's relationship to you, the location they work at, and what role they work in. In many cases, these relationships are not a big deal, and the financial just wants to be aware of them. Go ahead and share your connections!
