I am a junior and have an offer for this summer but don't want to go to the firm full-time. I added a minor, which pushed my expected graduation date back to Dec 2020 instead of May 2020. My school added classes for my minor, so I can still (and want to) graduate in may 2020, but a very prestigious buy-side firm is recruiting me for summer 2020 assuming my expected graduation date is still Dec 2020. Since at the time I talked to the recruiter, dec 2020 was going to be my graduation date. The firm is flying me out to their office so I can meet their employee's/group and interview, but if I don't get an offer, would it be unethical if I still graduate in May 2020?
