Confused regarding second round of interview

Hey everyone!

I interviewed for a summer internship position with the PMs for one of the funds. The interview went quite well and I was informed that this was the first and the final round. However, a few days later I was told that another funds PMs would also like to speak to me.

I am a little confused regarding this second invite. Does this mean they are quite happy with me and want to see which fund I fit better in and is the final sanity check and they'll place me in one of the two funds? Or is this another technical round? How should I prepare for this?

Any tips and advice is highly appreciated!

Thanks!
