I've been invited for a first-round interview at Roland Berger. However, Accenture gives me the opportunity to come work for them (interviews are over, they offered me a contract). I also applied at McKinsey, Bain and BCG but only Bain invited me for an interview, which ended at the second round. Should I tell them about all this? Will mentioning the Accenture offer do any bad, since it is not in strategy consultancy?
