Skipping the gap between an internship and a fulltime start

Maybe some UK IB ppl can refer. Is there a way to join fulltime, right after an off-cycle internship in IB at a BB?

I started an off cycle internship after bachelor graduation, saying I will do a masters (to be eligible in the first place). Now I don‘t want to do a masters. I would like to directly join fulltime after the end of my internship.

Has anyone done that before? Is it possible? And if yes, how?

Cheers
