I am an experienced oil and gas engineer who recently completed my first round of interviews for an O&G analyst position at McKinsey. I have to say that my first case interview went well, even though I was given a banking&finance-related case (interviewer-led style). The interviewer even said that I structured my analysis correctly and deliver the right answers. However, I believe that I did not perform well in the second case interview which was held yesterday. The second case was an O&G-related problem, candidate-led style, and I believe I was going too deep into the technical details. At the end of the interview, the interviewer told me that while I have a great understanding of the O&G industry, I have to structure my thoughts better and practice more cases for the next interview. I haven't got any information regarding the outcomes from this first round of interviews, so could anyone kindly inform me whether McKinsey will give you additional feedback on your performance, or you will be just getting a rejection/announcement email? I plan to keep on practicing mock cases for future opportunities, but I thought feedback would be very good to understand my weaknesses (in addition to structuring my thoughts better).
Thanks in advance.
