BCG LAGOS ONLINE INTERVIEW

Question

Please I'm having an interview with BCG Lagos soon, I need help on materials that can help me in preparation.

Answer 1

Hi there,

Honestly, all of these online tests are very similar

Format? Somewhat different. Content and what's required from you ability-wise? The same.

The best way is to really find online tests / questions and practice. Regardless as to whether is a new or old test, the principles are mostly the same:

Time management (need to think quick)
Business knowledge/context (incl key formulas)
Critical thinking (answers that are very similar to each other...clues "hidden" in the text)
Ability to interpret data/charts

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.

The (old) McKinsey PST, BCG Online Test, Bain SOVA test, etc. are all quite similar so leverage resources across all of them.

Answer 2

Hi there,

Q: I'm having an interview with BCG Lagos soon, I need help on materials that can help me in preparation.

In terms of general preparation, I would recommend the following:

Define a calendar for your preparation. Identify how many hours you have before your interview and allocate a time slot for preparation in your calendar for each day, working on the points below. Many candidates need 100+ hours to be ready before the interview starting from zero so you can keep that as a benchmark.
Start reading good MBA Consulting Casebooks – 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 insights. Try to read 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/casebooks 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 which ones you are repeating. This is very important, as otherwise you may do a ton of cases without fixing the real issues. If you find common mistakes, try to identify the reason for them (feedback from experienced partners would be particularly useful for this). Be sure to focus on both the behavioral part and the case part during the mocks. The case part should also cover market sizing, math and graph analysis.
Before the interviews, be sure to prepare your questions for the interviewer – a great way to show you prepared in advance and to connect with the interviewer for a good final impression. Ideally, try to get information on who they are and study their profile to have good questions to ask.
If you have to take the BCG Online Case (also called Casey Chatbot), you can find some info on how to prepare here and a full simulation at the following link: BCG Online Case Software Simulation

If you want to spend a few hours only instead of 100+ and cover everything mentioned above, I developed a program precisely for that.

Answer 3

Hi there,

I think this is an interesting question that may be relevant for many people. I would be happy to share my thoughts on it:

First of all, given that BCG mostly uses the BCG Casey pre-interview assessment, the rest of my answer will focus on this. Still, I would highly advise you to reach out to the recruiter to inquire about the specific format of the "BCG online test" since this is a rather vague term.
The BCG Casey pre-interview assessment is essentially a case study that you solve on your own. As such, I would highly advise you to focus your preparation on practicing case studies with peers and on your own, as this is the best way to prepare for it. In case you can get your hands on authentic BCG Casey sets, this could help you further, but I do not see any point in purchasing any guides.

If you would like a more detailed discussion on authentic BCG Casey sets, please don't hesitate to contact me directly.

Best,
