The interviewer is looking at your specific education and structured training credentials to determine your educational qualifications for the financial quantitative analyst job. They're also seeking to understand how open you'd be to further training as your career warrants or as the job requires. Your response should be enthusiastic and give an overview of the specific training you've had, how it was acquired and any future plans you may have in mind. Education can be a major part of a hiring decision so make sure you have copies of documentation such as diplomas, certifications, or other credentials that you can leave behind with the interviewer as proof of your accomplishments.
