Hi there,
The transition is definitely feasible although unusual – normally people move the other way round from consulting to PE.
Most people need 100+ hours to be ready for MBB offers. You will join as BA if you have 1 year of experience (they may recognize some months of seniority but that’s rare).
I would recommend the following steps to maximize the likelihood to land an offer:
- Define a calendar for your preparation. Check if there is any deadline for the applications. Then identify how many hours you have before that and allocate a time slot for preparation in your calendar for each day, working on the points below. Many people need 100+ hours to be ready before the interview so you can keep that as a benchmark
- Read Case In Point or Case Interview Secrets for a general understanding of what a consulting interview is. Don’t focus on the structures proposed in the books, as they are not good enough nowadays.
- Start reading good MBA Consulting Handbooks – you can find several for free online (Insead is a good one to start). Read the cases and try to apply your structure to solve them. Whenever you see there is something missing, upgrade your structure with the new insides. Try to read at least a new case per day – in this way you will absorb better the information with constant learning.
- After the first 5-10 cases in books/handbooks and basic theory, start to practice live. PrepLounge can be helpful to connect with other candidates for that. There is a relevant part of the interview score that is based on your communication, which you cannot practice at all if you read cases only. Keep track of your mistakes and see if you repeat them. If so, try to identify the source of the mistake (feedback of experienced partners would be particularly useful for this). Be sure to focus on both the behavioural part and the case part. The case part should also cover market sizing, mental math and graph analysis.
- Before your application, be sure to review your CV and Cover, so that they are in the required format for a consulting application
- At least 3 weeks before the application deadline, start networking to find referrals for your target companies.
- Before the interviews, be sure to prepare your questions for the interviewer –great way to show you prepared in advance and to connect with the interviewer for a good final impression.
Besides that, you may have to prepare for tests. Usually one or two weeks are enough for that. If you have to prepare for the McKinsey Imbellus, you can find the guide I created at the link below:

If you want to spend few hours only instead of 100+ and cover everything mentioned above, I developed a program to precisely do that. You can click on the following link to find more:

After this program, you will know exactly what to expect in your interview, what to work on, and how to focus on the real differentiator to land a top consulting offer.
Please feel free to PM me if you need more information.
Best,
