Yes, this is something that should be applied especially for McKinsey interviews. Because the interview format is less linear, and interviewers may abruptly move you from one section to the next, it is vital to verbally state your hypothesis + issue tree early on to allow your interviewer to know what your thought process and structure are looking like. I believe Victor Cheng confirms this in LOMS and his McKinsey practice cases. Hope this helps!
