IB + Consulting • Rotational Strategy

HEAR ME OUT. I've got an Investment Banking SA position for summer 2022, and a graduation date of May 2023.

I'm wondering if I can also accept a FT Management Consulting job by graduating early (Aug 2022), and post-IB SA summer, I start working within Consulting FT. If I like it better than IB, I stay long-term and decline the IB FT offer. If I prefer IB, I work within Consulting FT until May, then join my IB FT position nine months later.

Any potential issues that can arise assuming that I keep it down-low and nobody talks? I'm only asking from a perspective of potential legal issues & getting caught specifically through the background check (no, the consulting role will not be on my IB resume). Also assuming I tell the bank about my early graduation circumstance and they agree to give me a year off before starting FT.

I'm trying to hedge my bets in case (1) I don't end up landing the FT IB job or (2) I end up liking Consulting better. Yes, I'm willing to live with the consequences of losing both offers (I'm confident in my abilities to keep silent, and I know the consulting group my bank uses) and no, I don't need any rebuke.
