Preparing for consulting interviews - practical guidelines and useful tips

In this post I want to share some tips on how to prepare for the consulting interviews and my experience working in the industry (I did summer internship at Bain, Moscow office and currently I`m working at Finalta, part of the McKinsey, London office).

I will focus on two main points – what competencies consulting firms are looking for and how to approach the case interviews.

Consulting competencies

There are 4 main competencies that consulting firms are looking for: problem solving, personal impact, leadership and drive/passion.

Problem solving it is your ability to structure complex problems, analyze different parts of them and then synthesize all the pieces in order to find the solution. Problem solving is what you are going to be doing in your every day job. 

Personal impact it is ability to influence people over whom you do not have any formal power. As a consultant, you are not a part of the client`s organization but you have to convince your client to do what you recommend them to do.

Leadership is about inspiring others. As a consultant, you work in teams. As you progress you get more and more responsibilities and people to manage, so inspiring them to achieve theirs best is crucially important.

Drive/passion – you have to be really eager to make a difference to the client`s business. Consulting job is not easy, both mentally and physically (challenging tasks, long working hours). Therefore, if you are not passionate about it you might struggle at some point. All in all, consulting firms want to be sure that you, first, can do the job, and, second, that they want to have you on a team and can put you in front of the client on the day one.

Case interviews

During the recruiting process you have to solve at least 4 cases (2 per round). Each case has 4 stages – clarifying, structuring, analyzing and concluding. At clarifying stage you have to make sure that you understood the case question. It’s absolutely okay to ask interviewer several questions (about client`s business, reconfirm the main objectives of the case etc.). Moving to the structuring stage (you are allowed to take 45-60 seconds to think about and draw the structure) it is important that your structure is mutually exclusive and collectively exhaustive. In other words, make sure you`ve covered all the main points and your points don`t overlap.

After you have agreed on structure, you are starting to analyze the case. Treat this part as a two-way conversation. As you go along solving the case, try to think “in slides” as majority of consulting work is presented on slides. For example, if you have to do calculations – make them in a table format, so it looks as a client-ready slide. Recommendation is a final part of the case interview. At this stage, you have to synthesize all the information you have so far and prepare concise summary. Usually the recommendation should not take more than 30-60 seconds (so called “elevator pitch”). Include your final recommendation, supporting arguments, potential risks and next steps. Good luck!

Kyiv as one of the largest regional air hubs

Nowadays when experts are talking about the drivers of the Ukrainian economy they mainly mention agriculture and IT. However, there are also other sectors that Ukraine can develop in order to strengthen its economy. In this article we are focusing on the transportation sector and, in particular, on the benefits of transforming Kyiv Boryspil airport into one of the largest regional air hubs.

So what are the advantages that Kyiv has over other regional air hubs, and what are the direct immediate benefits it can bring to the local economy?

There are three main reasons why we believe Boryspil can become a regional air hub. The main reason is geographical proximity of Ukraine to all major economic centers in Europe and Asia (figure 1). To illustrate this advantage let’s look at three alternative ways of travelling from Beijing to London – with stops in Dubai, Istanbul (top choices at popular air travel planning website Skyscanner), and Kyiv. According to The Travel Math web-site, the average distance of the flight Beijing-Istanbul-London is almost 1000 km longer than Beijing-Kyiv-London. Compared to Beijing-Dubai-London, the advantage of Kyiv is even more visible – the total route through Kyiv is 2700 km shorter.

The second reason is a huge transit potential of the Boryspil airport. In 2014 Boryspil accommodated only 6.9 million passengers. For comparison, Istanbul Ataturk airport, which is just 2 hours flight from Kyiv and has relatively similar geographical location, handled 57 million passengers in 2014. By passenger flow, Boryspil is also well behind all other major Eastern European airports. Speaking specifically of the transit potential, in 2014 only about 6% of total passengers at Boryspil carried by the major carrier were transit passengers, while at Frankfurt this figure was 53%, at Schiphol - 42% and at Heathrow - 35%.

According to the Boryspil airport information, variable cost which depends on the number of accommodated passengers, constitute only 3% in its cost structure. So increase in the number of transit passengers is a “net profit” for the airport as total costs virtually remain the same.

Also, if we compare Boryspil ratio of handled passengers to the population of the Kyiv city to other Eastern European airports and cities, such as Vlacval Haval Airport and Prague, Frederic Chopin Airport and Warsaw and Liszt Ferenc Airport and Budapest we will see how far is Kyiv behind. This ratio (as for 2014) for Vlacval Haval is 8.5, for Frederic Chopin - 6.1, for Liszt Ferenc - 5.2, and for Boryspil only 2.4. Even though this indicator is not the perfect one, it shows that Boryspil virtually doesn`t use its potential as a regional air hub.

In addition, as the result of economic downturn in Ukraine and sharp hryvna devaluation, the cost of workforce in Ukraine became the lowest in the Eastern Europe. Also, electricity prices in Ukraine are lower than in the Eastern Europe.[1] So, theoretically, the cost of running airport infrastructure in Boryspil should be considerably lower than in other Eastern European airports.

The third factor that goes in favor of our proposal is existing infrastructure and spare capacity. As a part of preparation to the Euro 2012, two terminals were built at Boryspil. Currently out of 5 terminals only one is in use. And even this terminal is used only at about 30% of its capacity.[2] So, even without any additional investment into infrastructure Boryspil can handle at least 3-3.5 times more passengers per year than it does now. If Boryspil can utilize the spare capacity, it can increase the number of passengers up to 21-25 million per annum. 

Now we will look at the potential benefits (the list is not exhaustive):

  • creating new jobs. If the airport works at full capacity, or at least closer to its potential, it will generate new jobs within itself;
  • development of the serving/related industries such as ground services, advertising, transportation to and from the airport;
  • increasing tourism. Increasing passenger flow through the Boryspil airport will inevitably lead to the increase in tourism. Some people will prefer to make a longer stop-over so they can visit the city. Especially it can be the case for passengers travelling from Asia to Europe or North America.

All in all, we affirm that Boryspil has a potential to become a regional air hub. Becoming a hub will boost local economy. If Kyiv wants to secure its place on the regional air map it should act fast because the main competing air hubs are developing too. For instance, the Istanbul Grand Airport company announced the start of construction of a new Istanbul airport with total capacity around 90 million passengers per year at the end of the first stage and up to 150 million passengers when the airport becomes fully operational. The first stage is expected to be completed by late 2017. The busiest Russian airport - Domodedovo - is also rapidly developing and planning to increase its capacity to 60 million passengers by 2023. So, time is playing against the Boryspil airport.
