Mine was something along the lines of "design google". I am not sure when it became common belief that these interviews amount to leetcode regurgitation. Either that varies greatly by org or I was completely out of step with interviewing culture the whole time I was there.
Coding / algorithm interviews are distinct from systems design interviews. The interviewer would have been told which of the two to do. If your question was "design google", it sounds like you were only being scheduled for systems design.
(Anyway, you'd never ask a system design question from an L3, and only very rarely from an L4.)
