New Grad re-recruit for MBB?

Hey guys, so I just graduated from a top target with an offer from a T2 consulting firm. I was very happy with the offer and am fortunate to have a job in this environment. My start date was delayed to February 2021 however and I was considering re-recruiting for MBB. I found a job at a F500 that was willing to take me on in a temp capacity to keep me busy until my start date. Would people suggest that I apply to MBBs and just say I am working at the F500 as my first job? If so, how does that process look like? Do I go through the OCR similar to what seniors have or do a more of a lateral process? I understand that I am lucky to have a job and would definitely be excited to start at the T2 but MBB is still preferable. 

I know Bain is less keen on laterals but reports indicate its more common lately? 

In terms of last recruiting cycle, I only got an interview from one MBB but made it to the final round. Not sure if things would be better this time around but worth a shot?
