I've read many many comments from consultants here stating that MBBs are pretty much the same and that the differences are marginal. Well, I would like to share my story and have your take on it.
I interviewed with all MBBs. got rejected at Bain's final round, and received offers from McK & BCG. I now try to decide between the two and when contemplating my process with each one I notice a major difference in my experience between the two.
McK
HR: Behaviour was questionable. My interviews were rescheduled three times which is ok, but the thing is HR changed the dates on her own mind without even asking me if the new date suits me, and casually informed me they had to move it. Also, the overall communication was very distanced and formal.
Networking: I Approached 10+ consultants from the office via LinkedIn, only 2-3 responded, had two calls which were ok. When I asked if it was possible to have a mock case interview was told that they are really busy and can't. later when preparing for the final round I messaged them and got ghosted.
Interviews: All interviewers were very impressive people, but the conversation felt distant and like there is no real interest in me as a person, only to understand if I check their boxes. Also, at one interview the interviewer was extremely not nice, seemed to be angry for some reason, and had overall really bad vibes. Also, at no point did I have an HR interview which I find odd.
BCG
HR: Was super nice from day one, took a genuine interest in me. Took the time to explain everything, and any change that had to be made was communicated beforehand to make sure it was ok on my side.
Networking: I Approached 10+ consultants from the office via LinkedIn, had 7-8 replies, had 4 phone calls with consultants that took the time to explain to me a lot of things about the job and the office. One of them even circled back to me after two weeks to asking how was my process doing and if I'd want to do a mock interview, without me even asking.
Interviews: Had a blast in all interviews. The conversation seemed genuine and went both ways, the people were very nice, and not distant at all. I clicked with an MDP that made the interview feel like we were on the same level and was genuinely curious about me. Also had an hour-long HR interview that made me feel that personal fit is extremely important to them.
Synthesis
Overall there was a stark difference in my experience at both firms. McK felt really distant, with a clear hierarchy, and very very formal. Also, the behavior to me as a candidate was questionable. Whereas the process at BCG felt fun and inviting. the people were extremely nice (all the way up to MDPs) and the overall atmosphere was great.
This obviously makes me inclined to opt for BCG but I have two considerations about it:
1) What if that's just an anecdotal experience that won't represent my experience working for these firms? As I noted in the headline, most consultants seem to agree both firms are more or less the same.
2) Regarding prestige and pay, McK is considered more prestigious overall, and pays ~10% more in base salary than BCG.
