There are 2 rounds of interviews, both of which have 2 back to back interviews (4 total). Each interview has both a behavioural and a case component, which are roughly 20 minutes each.
Interviewers vary in style and difficulty but in general I found the interviews to be challenging / rigorous but fair. The interviewers are generally very warm and open.
Interview questions [1]
Question 1
Tell me about experience X (on resume). What are the biggest lessons you learned from that experience?
3x case interviews, interviewee led, questions about experience and relevant background, always dig deeper to understand details eg on leadership experience. Cases vary all the time, need to ne ready for anything. Thinking js rewarded
Case interview about merger and acquisition
Was medium difficulty has a lot of brainstorming and analytical elements
Required quick thinking structuring and deep analysis to really ace it easily
Practice is def mandatory and failure to do so will lead to failure
I applied online. The process took 2 months. I interviewed at Boston Consulting Group (São Paulo, São Paulo)
Interview
Prova GMAT+ Case + inglês seguida de duas rodadas de duas case interview. Entrevistas bem desafiadoras e exigentes já que o entrevistador somente responde suas perguntas e não dá muitas informações sobre o case.
