That is true. It is myth interviewers do not hate frameworks in case interviews. Interviewers dislike the way the framework is introduced and used by the candidate. Most candidates memorize a framework, look at a case, see the loose link between both and gladly offer the framework without a proper explanation or even making adjustment to the framework. The best approach is to brainstorm unique structures for each case. However, where this is tough to do, candidates should take time to carefully adjust and integrate the framework into the case, using good communication skills.
