"Being an upcoming new graduate, I cannot say I have received any customer service-specific training. My retail and hospitality experience in high school and college taught me the basics of customer service, making me very well-rounded. I would be happy to take any training you recommend and would love to hear more about your specific training program."

This training could include a robust onboarding plan, on-the-job training, courses taken, or even books you have read in your spare time. Show the interviewer that you are interested in improving your customer service delivery. If you have had direct training in customer service, talk about it in detail and what skills you learned that you can bring to Centene Corporation. If you have never had direct training, no need to worry. Just reiterate your experience as the best training possible.
