What should I prepare for the BCG fit interview?

In general your answers should be 1-3 minutes long (depending on the question and body language of the interviewer). Remember, you need to be prepared with answers for "Resume Walkthrough", "Why consulting", and "Why BCG". Furthermore, you need to have 5-7 stories prepared.

You should expect 2-4 questions.

Resume walkthrough

Needs to be chronological

Only keep important details that make you look good (i.e. I worked across 7 industries and rose up the ranks twice in the course of that role)

Keep a theme of "why consulting"

I.e. at each step you need to show that you both got exposure to aspects of consulting AND thrived + enjoyed them

Finish with: And that's why I'm here today looking for consulting with your company

Why Consulting

You need to summarize what you did before along the theme of consulting aspects you liked and consulting aspects that were missing

You then combine those two - i.e. I know I like + am good at x, y, and z which is required for consulting, and I really am excited to get a, b, and c

You finish with a "mini" why x company

Why x company

Start with a "mini" why consulting

Then have 2-3 reasons why x company is your target

Every "reason" needs to incorporate 1) That you know they value x 2) That you not only value x but have exhibited it and done it in the past

Be very very mindful of what they want you to want
