Ideal situation

My younger sibling's friend is asking me for advice, she just signed an offer for McKinsey for their sophomore program and is considering recruiting for banking. What groups would be worth it - especially if it is McKinsey NY? The program has a very high return rate offer. Furthermore, she is considering looking potentially do a role in tech, but doesn't want to discount the value of a banking internship. Any help is appreciated - I'm not very involved in the recruiting space or what could be valuable for her (she goes to a target West Coast school).
