BCG/Bain SEA: Does R1b invitation confirm R1a pass?

Question

I recently completed R1a at both BCG and Bain SEA, and have been invited to do R1b for both next week.

For Bain, HR explicitly told me I passed R1a, and that's why I'm being moved to R1b. The recruiting guideline stated that "advancement to the 2nd interview is dependent on performance in the 1st interview," which reads as if each interview has its own separate pass/fail decision, rather than both being evaluated together at the end of each round. I'm not sure if BCG works the same way or differently. I also know candidates who did R1a (at either firm) but were not invited to do R1b, which adds to my confusion.

For context, I was fairly confident about my BCG performance, but for Bain I think it was more borderline — my structure wasn't well scoped, and I didn't drive the case as strongly as I had hoped. Nonetheless, I managed to solve both cases.

Questions:

Is an R1b invitation a genuine pass signal for R1a, or is doing both interviews just standard practice before any evaluation happens? Does this differ between BCG and Bain?
When deciding advancement to Round 2, are R1a and R1b scores combined, or is it solely from R1b result?

Would appreciate any POV from MBB SEA recruiters or anyone who's been through this process!

Answer 1

Hi,

1) At BCG, the interviews in the same round are run independently. Each interviewer scores you on their own, without knowing how the other one went. That means you could have done badly in R1a and still be invited to R1b, so the invitation is not in itself a pass signal.

2) You need to pass all of them. Both interviews have to clear the bar to move to Round 2. A strong R1b will not rescue a weak R1a.

So treat next week's interview as fully decisive on its own, and go in driving the case much harder. That is the gap you spotted yourself.

Answer 2

Hi there,

First of all, congratulations on the progress in the application processes with BCG and Bain thus far!

I would be happy to share my thoughts on your questions:

First of all, I would strongly advise you to either of two options: 1) not spending any more time on pondering the application process and instead focusing all your energy on your potentially upcoming interviews or 2) reaching out to the recruiter since only they will know for certain, to gain clarity.
Moreover, contrary to what other coaches have said, assessing a candidate is not an entirely quantitative process. While there normally always is an individual quantitative assessment, the actual decision is made in the recruiting committee. This means that eventually, all interviewers need to agree to you progressing to the next/final interview round, and a truly weak performance in one case study can often times be enough that at least this one interviewer will not agree.

If you would like a more detailed discussion on how to best prepare for your upcoming BCG and Bain interviews, please don't hesitate to contact me directly.

Best,

Hagen

Hi,

Used to be from BCG SEA.

For BCG, R1a and R1b are conducted and then assessed together, before deciding to pass you or not to R2.

For Bain, back when I was interviewing, it was sequential (e.g. i had to take each interview and the decision for the next round would be dependent on each interview).

Hope this helps.
