Challenging but fair. If you have good understanding coming in you'll be fine (but need to know concepts not memorized answers). I'd prioritize having a general understanding of the market as well.
Two 30 minute interviews and a super day with two back to back interviews. Everyone I spoke to was freindly and put a big emphasis on finding a cultural fit. The technical questions were expected and no curve balls.
