2 weeks to go

Question

Hi all,

My R1 interviews for BCG Platinion are scheduled in roughly two weeks.
As of now I've practiced casing (full cases, drills and maths) and personal fit a lot - for about 6 weeks, feeling confident.
Currently I am not sure what to focus on in the next two weeks.
So first question, what would your advice be for this period of time?

My biggest concern comes from the fact that there a few "real" cases which are digital related. So I've prompted GPT to give me case prompts, exhibits etc.
So second question - Do you have any experience on how well it does for prep? Generally you opinion on that interests me.

Thanks!

Hi there,

Two weeks out is a good place to be, especially since you’ve already built a solid foundation. I’d suggest the following focus areas for the next stretch:

1. Sharpen, don’t overload

Keep practicing, but shift from volume to quality. Do 1–2 high-quality cases per day, then spend time debriefing deeply (what worked, what didn’t, what patterns keep recurring).

2. Drill core skills daily

Mental math and chart reading: quick daily drills to keep speed and confidence high.
Communication: practice structured, concise answers to “walk me through your thinking” and synthesis questions.

3. Personal fit refinement

Have 4–5 strong, flexible stories ready (leadership, impact, conflict resolution, resilience, why consulting/why digital). Rehearse them so you can deliver naturally and tailor depending on the question.

4. Mock interview focus

Do at least a few mocks with peers/coaches in the last week to simulate pressure. These will surface weaknesses you may not notice on your own.

On your second question:

GPT can generate helpful prompts and exhibits, but the quality varies. It’s good for volume and creativity, especially if you want to see digital-flavored setups, but don’t rely on it 100%. Sometimes the math or logic can be unrealistic.
Use it as a complement, not a substitute. Treat GPT-cases as practice for structuring, brainstorming, and reacting to exhibits, then cross-check against official casebooks or peer mocks for realism.

Happy to help you prep – feel free to reach out.

Best,

Evelina

Hello, congratulations on your interviews! Two weeks is plenty of time to get everything sorted. Here’s what I would do.

My main advice for this stage is to shift your focus from doing a lot of cases to doing them better. You've already done the hard work of building your skills. Now, it's about refining them and building confidence.

The most valuable thing you can do now is get in as much practice as possible with real people. It's the only way to get real-time feedback and practice managing the pressure. After each mock interview, ask for specific feedback on your weak spots so you know what to work on.

You should also spend some time drilling your weaknesses. If you know you're not great at mental math or structuring, practice those things specifically. And make sure your fit stories are polished. Have a few core stories ready to go for questions about leadership or conflict, and practice them out loud so they sound natural.

As for using GPT, I think it’s a great tool, but not a replacement for a human. It's perfect for generating practice questions, especially for those specific digital cases that are hard to find. It's like having a textbook with an infinite number of problems.

But it can never give you the most important thing, which is nuanced human feedback. It can’t see your body language or feel the pressure you’re under. It can’t give you the honest critique a real person can. So, use it to get your reps in, but make sure the real practice is with a person who can prepare you for the live interview.

You’ve got this!
