I initially applied for the McKinsey "Insight" program and was invited for a telephone interview (I submitted a full academic CV (4 pages) since they asked for it and I have a PhD). The telephone interview involved a small fit portion and a case for 30 mins. The fit portion went well but I bombed the case and was not invited for the program. I was disappointed but this failed interview led to full-time Associate interview in the Fall of the same year WITHOUT me having to resubmit my CV and hence go through a CV short listing process. Also, I was given an option to interview 1 month earlier than the regular fall interview process, which does not provide an advantage but you could have a early job offer, if you get it. 1st round (Boston): PST and 2 team cases. You can find information regarding PST everywhere in the internet and as mentioned everywhere it is tough and prepare well for it. Time management is key and make sure to answer all questions. The team cases were regular case interviews led by associates or senior associates from McK. Be proactive and enjoy the process. 1st round decision: You get to hear within a week if you get through to 2nd round 2nd round (Boston): 2 case interview with Senior Associates and/or Engagement Mangers and in a rare case with Principals. 45 mins long with PEI and case component. Not tricky cases if you have done enough practice. Be confident, be clear, be structured and do your math quickly and efficiently. For APD candidates they value your confidence and sharpness a lot. 2nd round decision: You will get to hear within 3-5 days if you get through to final round Final round (New York): 3 interviews with Junior Partners (Principals), Partners and Directors (Senior Partners). Essentially exact same format as round 2 but unstructured. Hard to tell what they are looking for at this stage. Be yourself, enjoy the process, make it conversational and nail the math. Make sure your are confident and lively throughout this process. If you dont enjoy the interviews you will not enjoy the job. Final round decision: You will get to hear the same day if you make it. If you dont hear the same day MOSTLY you did not make it, but still a small possibility. Practice at least 50 cases before the interviews with people who know what the hell they are talking about and not random people
