How feasible to get an international transfer? ( BCG)

Hey all,

I'm a recent grad about to start FT at BCG in a Northeast US office. Eventually, I'd love to spend some time in the London office, ideally a ~6 month transfer. I know BCG has a few different options for international exposure. Could anybody expound on what those are and what the processes are like to participate? Are you able to do them at the associate level/what does the timeline look like?

Thanks!
