McK SBA Partner Round Short Interview

Hi everyone,

I’m currently interviewing for the Taipei office summer internship. Today, I had an R2 interview with a partner from the Hong Kong office.

After a brief mutual self-introduction, we went straight into the case. There was no PEI. The case was a fairly standard M&A / acquisition evaluation case.

After presenting my framework, we moved into market sizing. Before and during the case, I asked several clarifying questions, and the interviewer said multiple times that they were good questions. During the sizing, I walked him through both my calculation logic and the actual calculations, and I also interpreted the final result once I was done. He gave positive verbal feedback throughout, saying things like “good.”

Once I finished the market sizing, the interviewer ended the case and moved directly into Q&A.

At the end of the Q&A, he specifically told me not to be discouraged that the case ended early, as he already had all the information he needed. In total, the interview lasted around 30 minutes.

I’m trying to understand how to interpret this. Is an early ending in an R2 partner interview usually a negative signal? Also, for McKinsey final rounds, is it typical to have only one R2 interview, or should I expect another partner interview as well?

Thanks in advance for any thoughts.

Hey,

Let me answer based on my McKinsey experience:

1. Only one interview in R2: yes, this would be unexpected. However, this is not unheard of, especially if the Senior Partner is a key leader (e.g., the Recruiting leader for the office, or the leader of a specific practice)

2. 30 minutes: as you describe it, it seems that the interview went very well. However, you can never rule out that he was just busy and needed to, say, use the last 15 minutes of your slot to call a client :)

Hope this helps!

Hi,
I would not overinterpret the fact that the interview lasted only 30 minutes. As an interviewer in final rounds myself, I have shortened interviews many times for many different reasons: rescheduled client meetings, emergencies, timing constraints, or simply because I already had enough information from the candidate.

And “having enough information” can honestly go both ways; positive or negative. Sometimes it is performance-related, sometimes it has nothing to do with the candidate at all.

From what you described, though, the signals seem generally positive.

Regarding having only one final round interview, yes, it is somewhat less common, but it can definitely happen. It often depends on practical variables such as interviewer availability, office process differences, your first-round performance, ...

So I would not read too much into that either. At this stage, there is unfortunately not much else you can do besides waiting for the outcome.

Best,
Franco

Hi there,

This sounds like a very strong interview performance!

Based on how you're describing the process, I would rather read 'positively' into it. Most likely you had a very strong performance and the Partner didn't feel the need to dive deeper. This does happen sometimes, especially if they also feel pressured to manage time on their side (as in, they have other commitments that day). 

What is surprising is that you didn't cover PEI at all, because that's a requirement. 

For now, I suggest you congratulate yourself on the effort and wait to hear back from them. Hope you'll get good news soon!

Best,
Cristian
