Hi there,
I agree with Nikita, it seems your profile is seen as more related to the researcher role than the consultant one. It could be that your CV was not tailored to showcase your potential as a consultant, have you got feedback from an experienced partner/coach on that?
At McKinsey I have seen this happened with 3 friends of mine. They all accepted the researcher role and became consultants (BAs) after about 2-4 years. However, this is not guaranteed, most researchers remain in the R&I department and make their career there. Also, 2-4 years may be a long period of time. Salaries are also lower (in Brazil, about 30% comparing an R&I analyst vs a first year BA). The upside is that usually the lifestyle is better (almost no traveling, fewer working hours) and the job is also interesting.
If you are not interested in this position, signalize it to the recruiter and apply for other companies to have a backup plan.
Good luck!
Best,
Mari
