I have been rejected by BCG because of "lack of motivation". For the rest of the interview, the feedback was positive.
Obviously, I didn't transmit my motivation to my interviewers... Since I have McK interview coming soon, what things should not be "said" in the "why consulting" questions? I fear my error might have been saying I only applied to BCG and McK... Making them think that maybe I wanted only the name of the company... Another option might have been not asking "bright questions" in the Q&A...
Unfortunately, I didn't ask for more precise feedback during the feedback session, so I don't have much to reason on.
