I am an industry hire (O&G, 5 years exp). I gave my second round interviews with BCG 2 weeks ago (2 interviews with partners). A week after the interview, I was told that they wanted me to give another interview with the partner in the energy practice, given my background. I gave that on Tuesday and it went well, except that I made a mistake with a graph I was asked to draw but I recovered and corrected myself quickly. I was just told by the HR today (Friday) that she has feedback from all the partners who've interviewed me but she cannot give me an update or result because the recruiting directors and the partners need to get together to make the final decision.
Could it be that they were on the fence about me and my mistake in the third interview is making them hesitate more? Does it happen usually that the partners are not really sure whether they want to extend an offer or no? Or does it bode well that they haven't rejected me yet?
