This question is truly a slippery slope. Like any question during an interview, you are expected to provide an answer, but be very careful about your response. Any major financial issues you do have can be discovered during a thorough background check, and if a check has been done before your interview (rare, but it does happen!) you may want to ask your interviewer if s/he is looking for something in particular. No matter your true circumstances, you don’t want to project that you can’t manage your own finances, particularly if the position you’re applying for involves money, security or legal responsibilities. You really want to diffuse this question as fast as possible. Optimally, you should be able to confidently state that you have no problems taking care of your financial responsibilities. But if there are issues, or something has been uncovered in a background check, don’t lie. Keep any explanation as brief as possible, and respectfully try to convey that the question is not relevant to your ability to do the job for the employer. Be careful! And as always, keep your answers relevant to the job you are applying for.
