What to expect in HF PM/Founder Interview?

Hi all, I'm interviewing for 2 Associate PM jobs. Both are fundamental generalist coverage jobs. One call is with Fund A's Founder and CIO, the other is with Fund B's PM + Analyst, but not Senior PM.

Fund A is global equity. Fund B I'm not sure, maybe more like an index closet fund because its AUM is big. 

I got both interviews by sending cold emails with 1-2 investment memos. I have about 4 stock pitches with me. 3 very detailed. 1 is more high-level since it has come to fruition very recently.

What should I expect for these interviews?
