Yes, expecting them to know that is reasonable. Expecting them to regurgitate that factoid unprompted is bullshit.
Don't inquire on a topic and expect a canidate speaking in generalities and off the cuff to overlap with your toy facts.
I'm fighting the urge to rant in the comments here on how to competently conduct a useful technical interview; but I'm more and more convinced it's a competitive advantage.
To be fair, it also sounds like you were conflating popular hash functions like md5 with the general concept of a hashing data structure and underlying function. Knowing that modulus operation is one approach and knowing common approaches for dealing with collisions are part of that. See: https://www.geeksforgeeks.org/hashing-data-structure/
