First, reach out to HR to get a specific breakdown of what to expect for each interview round.
Why go in guessing?!?
Second, you should be prepared for any of the following (but won't necessarily have to do them all):
1) Bain Online Test
2) Behavioral / Fit
4) Bain Written Case
Third, here's how you prepare:
Think of it as a merge of a case and the GMAT/GRE.
You need to be clear on some key case-related and account formulas (margin, growth, breakeven, etc) as well as be good at critically understanding the question (including nuance to questions) and parsing through complicated text with a fair amount of distraction.
You'll also need to be good at chart/graph reading.

There an excellent guide:
I also have a practice test - shoot me a message and I can send it your way!
And here are some sample questions:
- 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
- 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
Step 1 - Categorize the main stories
There are 5-10 "themes" you need to prepare for. i.e. Leadership, teamwork, challenge, etc. Figure out this list and make sure your stories cover this range (PM me and I can provide you with a template for this list)
Step 2 - Create FLEXIBLE stories that cover a range of categories
You need to create 4-6 stories that each cover a range of topics. They need to be powerful stories that can be adjusted and adapted based on the question asked.
One of my "core" or "killer" stories was usable for Initiative, Achievement, Leadership, Challenge, Change of direction, AND Persuasion.
Write down these stories along STAR or similar format...use bullet points
Step 3 - Organize these stories so you know which ones can be used for what and PRACTICE
Make sure you cover the whole gambit. Then, practice getting asked a question and thinking of which stories apply. I can assure you, no-one is coming up with full stories in a few seconds. Rather, they have practiced how to adapt an existing story to the question asked.
Well, this is a big topic ;)
