I'm sorry if this is a silly question. I'm still relatively new to the consulting world and the application system. I applied to BCG, Bain, OW, ATK, AlixPartners so far without a referral but continued to network with people from some of these companies. I'm not sure whether it is too late for a referral to be of value now that my CV etc has been submitted? I have not asked any of the people I spoke to as had already applied. I have not heard back from any of the above except Bain which has called me for first round interviews.
