Yes, it is reasonable to ask about the interview format.
Recruiting may tell you the general structure, but individual interviewers can still vary in how they run the case.
Use the answer to guide preparation, not to narrow your prep so much that an unexpected variation throws you off.
The core skills remain the same: clarify, structure, analyze, communicate and synthesize.
