Case Interview Preparation & Management Consulting | Strategy | Critical Thinking

Too often clients ask the wrong questions when it comes to assessing training at consulting firms: do smaller offices have poorer training, should I attend training as soon as I join, does BCG have better training than Bain etc. When considering training you need to both consider formal and informal training. As we show, formal training is very useful, but not at all for the hard/technical skills it purports to impart on attendees. Informal training, also known as training on an engagement, is most effective when consultants can practice under diverse conditions. In other words, the more you travel and work with foreign teams, the better will be your training. Some firms encourage more global staffing and others far less. That counts.

Reading graphs is a perennial problem for many candidates. Yet, the problem is not the interpretation of the graphical data itself. Rather, it is knowing what to do with that data once you have interpreted it. This podcast introduces a simple 4-step process we introduced for a Yale doctoral client, Felix, and a technique called the One-Sentence-Test which we again developed for the same client. The improvement in her answers warrants sharing this technique. You can see Felix's Improvement in Season One of The Consulting Offer.

The first podcast discusses a common challenge new consultants face: how to show strong analytic skills on an engagement. Here I discuss one of my earlier engagements as a principal where I managed a very introverted lawyer. Despite her non-quantitative degree, reserved demeanor and being placed on a piece of work which was not, at first, open to much creativity, she developed an eminently analytic way to solve a significant problem impacting the entire engagement. This is probably one of the most concise, tailored and innovative pieces of analyses I had ever seen in my career. What makes a consultant analytic, is not the type of work that lends itself to analytic reasoning, but the way you approach what may seem to be a mundane problem. In fact, no sector or engagement is boring if examined appropriately.

This podcast answers the questions raised below, by a client trying to understand how to develop hypotheses in a fairly difficult case. The case looks at ways to increase the US Postal Services market share and profitability. The client has graciously allowed this one detailed response and his notes to be shared in our public section. “A big overarching question I have with the answer first approach is I don’t know if my initial hypothesis should be broad (in which case they cannot be tested with data unless the hypotheses are first refined and narrowed, so I could only ask what areas I would explore to do that) or alternatively to make my initial hypotheses narrow and precise (in which case I can ask for data to test them but if my hypothesis are wrong then I will be stuck). Any thoughts?”

In this podcast we will discuss a client who is very good at influencing the way interviewers work with her, and the subtle danger of her approach. A counter-point to this is another candidate who initially completely mismanaged his image, and we discuss the impact of his actions and what happened when he changed.

In looking through our database of over 240 former clients and speaking to Bain partners we know, we see two unique ways a Bain fit interview differs from a McKinsey PEI. The first relates to way in which you interact with the interviewer as you deliver your response, and the second relates to a very specific attribute that Bain seeks in your fit responses. Both differ substantially from a McKinsey or BCG interview. In fact, EVERY single client we placed at Bain strongly displayed these two characteristics. It is uncanny how close a correlation exists.

Bonus versus salary resumes, is a very simple test we do on resumes. This podcast explains the test. We basically look at whether or not a bullet point explains an action which earned you a salary or would have resulted in a bonus. The latter is vital and the former should be purged from your salary. McKinsey looks for things on your resume which earned you your resume. It is important to understand that merely doing your job is not an achievement in itself.

The economic impact of poor business judgement, is a topic we managed every day as partners. Each time an associate made a poor “common sense” decision we needed to explain both the potential reputation and economic damage done to the firm. The former is well-known, but the latter is less known but just as important. In thinking through why consulting firms look for business judgement, it helps to consider the economic impact to clients and the firm.

Building of our technique to develop hypotheses, this podcast explains a clever way to generate creative hypotheses. In essence, the podcast will be useful to candidates who have already seen how we brainstorm and generate hypotheses, since this podcast expands on that thinking. The core of this idea is that if more than one structure can be brainstormed for a case, each of those structures can be used to develop a new type of hypothesis. This is a very, very simple technique as well.

In this podcast present a clever technique to treat graphs as “maps” when reading them. Corporate Finance candidates will like this. The key to this technique rests on the simple idea of ignoring the data plots and first trying to understand what the type of graph is saying. Once this is clear, the data is then examined within the graph to understand its meaning. The podcast explains this with an example and is a very effective tool we use for teaching clients.

We always ask our clients, especially those from weaker schools, to network with the most senior partners of consulting firms. This is a podcast about a PhD client, from a weaker school and no existing consulting relationships, who painfully followed this advice over several months to network with a member of McKinsey's worldwide leadership and obtain interviews for his office of choice. It is not easy, but can be done. It works.

Lots of candidates leave it to the interviewer to determine the energy levels, tone and mood of the call. That is a bad idea. In our experience, the best candidates always bring a light mood to interviews. Seriousness, can hurt you as it is confused for anxiousness. Delegating the mood to the interview is bad idea since it means the energy of the case will be largely out of your control. Moreover, unless you practice controlling the energy, it is unlikely you will have this skill to deploy in the case interview itself.

Due to culture, tradition and even good intentions, candidates make sexist remarks. Sometimes, a very innocent remark may come across as sexist. This podcast examines some the incidences we have encountered which have hurt candidates in cases. It is wise to think about your own inadvertent sexist behavior.

This extremely detailed podcast offers advice and information on the rise of Sub-Saharan offices – Nigeria and South Africa, the rise of African candidates, types of work done in these offices, the interview process and challenges faced by candidates, key partners, key clients, significant projects, hiring strategies, recruiting firms used, expatriate strategies and more. It is one of several detailed office podcasts we have released for the English-speaking offices.

This podcast looks at how to make estimations when calculating smaller values or working with enclosed spaces like restaurants, the importance of sensitivity analyses and a new limitation of demand-driven cases. This is a very important technique which can significantly improve accuracy and efficiency in case math.

Last week, an associate we placed at BCG emailed with a dilemma. A senior partner and managing director of the firm was visiting her office and she wanted to meet him. Her colleagues told her to forget about it as she was too junior to warrant his attention. Her peers who gave her this advice may have a few years at BCG but they clearly do not understand the culture of the firm at all. Senior partners always make time for consultants and are always looking to meet young and enthusiastic new employees. Giving the strict vetting process, when you join you are merely a young leader, never a young person. This podcast explains my views on this as a former partner.

Going into interviews aspiring consultants will be relying an a huge number of people for help: peers, classmates, consulting alumni, consultants, career counselors etc. This podcast offers some simple suggestions on how to seek and use help without hurting your relationships in the long-term.

A steep hurdle for many candidates is knowing how and when to ask for information / advice from an interviewer. To help our candidates, we developed the barter system / concept to fix this problem using a very simple technique. As explained in the podcast, the concept requires the candidate to first offer the interviewer their thoughts/ideas before asking for anything more. This ensures the candidate does not fall into the trap of asking for information without offering anything in return.

Editing out cliches from Deloitte and Accenture resumes tends to take up the majority of time when we work with candidates from these firms, and the other accounting firms like PWC, E&Y and KPMG. Typically, when we start the editing sessions, it is very difficult for the client to see how vague and misleading their resume really is. This podcast explains this concept and can be used to edit your own resume.

When learning cases, it is far more effective to watch a person on Skype or in person. The problem with merely practicing over the phone or another verbal format is that you cannot observe crucial mannerisms or allow your practice partner to observe you. The only time practicing verbally makes sense is when you have a very experienced person working with you and they can infer things about your performance based on their experience. We advice most clients to practice in person should the opportunity present itself.
