Quitting internship early?
Hello need some advice here
Am a junior currently. I am due to start a 6 month long internship next year (1H) with a MM bank, have already signed the contract and finalized the offer details. However, I just got an offer for a BB SA next summer. The issue is, the MM internship duration lasts up till July which is beyond the start date for the BB SA. I have spoken to HR at the MM bank and they have indicated that it is not possible for me to shift my start and end dates.
Not sure if this is a point to consider but there is also very low chance of a FT offer at the MM bank. Would it be a dick move to accept the BB offer and quit early in my MM stint (about 1-2 months early) or should I raise this to HR and potentially be seen as reneging? Ideally I want to do this in a way that burns the least bridges as possible
