Worries about SA 2024 Background Check

Hi all, 

I was fortunate enough to get an SA 2024 IB offer at a large NYC bank a few months ago, and have been stressing about my background check that is coming in the next few months due to how I presented my educational path on my resume. Here is the situation: 

Last fall, I transferred from a mid-tier private to an Ivy after 2 years at the other school, but due to a good amount of credits not being accepted and pretty intense distribution requirements of my new school, I'll be spending 3 years there, and hence doing 5 total years of undergrad–I didn't purposefully delay my graduation, I just didn't have a choice if I wanted to transfer to this new school, and I was put into the sophomore cohort of transfer students during advising, orientation, etc. despite having done 2 years of college already. On my resume, however, I only put that I "transferred from school X in 2022" as a single line under my education listing, and not the full dates of my enrollment there, so it isn't clear that I'll be spending 5 years in undegrad from my resume. The point was to emphasize my brand as being mostly from the current school I am attending, since it is significantly more prestigious and has a strong IB pipeline. But I am a bit worried that they will see this as being a form of "deliberate misrepresentation" and pull my offer, even though I didn't put anything that was untrue on my resume, as I did transfer into my current school in fall 2022. 

Will I be fucked for not making it clear it is taking me 5 years to finish undergrad on my application? I imagine they'll know once I have to send in the transcript from my old school and see I did 2 years there, and have some questions about that. No one in my interviews asked about it, though I did mention it to a few people I networked with when they wanted to know my backstory and experience transferring–during the interviews, they just wanted to know about stuff from my current school during the behaviorals. 

For people who transferred schools and did an SA in IB, did they ask for your transcript from your previous school during the background check? If they don't ask for the transcript from my previous school, I assume I would be fine, since my current school only lists the date of transfer into the school, and classes that transferred in.
