Hi there,
I would recommend the following:
1. Understand which are your areas of improvement – the sooner the better.
No one can provide tips on how you can get better if you don’t know yourself which are the possible improvements
- The “fast” way is to book a coaching session. However, that’s not free
- The “cheap” way is to find a good case partner that can provide great feedback
Whatever option you use, write down the improvements/mistake in an ad-hoc spreadsheet and use it as a reference for the next steps
2. Take the feedback and work on the improvement areas
- You may have to do drills on a specific part where you are weak (eg structuring or graph analysis)
- Update your spreadsheet after each case/drill
- Try to find cases/drills related to your improvement area until you are not repeating the mistakes
3. Refine your prep
- Once you have fixed the mistakes you are aware of and your current partners cannot point out additional ones (or if you cannot find ways to fix them), move to a new partner or a coach for fine-tuning
- Review the fit part - it is as important as the case, although it is easier to prepare. You can find more tips on that here: https://www.preplounge.com/en/consulting-forum/bain-london-can-anyone-share-insightsexperienceadvise-on-behavioral-interview-pastforward-looking-9156
- Prepare your questions for the interviewer
If you don’t have enough time to reach a good level, it is better to reschedule the interview. You should be able to get an idea of your level after step 1. When I do coaching I provide a score that points out exactly how far you are from a first and final round pass, but any good partner should be able to give you a general idea of that.
For additional questions please feel free to PM me.
Best,
Francesco
