Christian Fink, Senior Project Consultant, MEB Alumnus

How did you get in touch with E.ON Inhouse Consulting (ECON)?

I completed my Master in European Business in London and Berlin including the Master of Science track from 2013 to 2014. Having finished my thesis work, I wanted to get practical experience in consulting. My interest in the energy industry led me to apply for a three-month internship at ECON, after which I received an offer for a position as a Project Consultant. I happily accepted it, given the positive experience that I gathered throughout my internship, in particular the style of work and atmosphere at ECON.

What do you like most about ECON?

First of all I like the exciting projects at ECON. As an internal consultancy, ECON drives major strategic projects for the E.ON Group and at ECON you are a part of developing new strategies and turning them into reality. Even being staffed on a new project you can see how the strategy you have been working on evolves and what impact it creates. Additionally, I enjoy the working style at ECON: flat hierarchies and a strong feedback culture ensure a steep learning curve, supported by a broad training curriculum and a personal mentor satisfying individual development needs. However, most important to me is the friendly and collaborative atmosphere at ECON. It actually reminds me a little bit of my time at ESCP. We are a very international company with colleagues from 15 different nationalities, diverse backgrounds and we use English as the business language. Furthermore, I am not only spending time with my colleagues in the office. A lot of colleagues also became friends and we spend a lot of time together over the weekend.

Can you tell us more about your projects?

I worked on exciting projects in business development, driving efficiency or in digitalization. During my last project we founded a start-up company for Internet-of-Things-solutions in Berlin. It was really exciting to witness the whole process of strategy development and implementation, while navigating all operational challenges coming along with founding a new start-up. Currently, I am supporting E.ON’s Digital Transformation with a focus on Marketing and Sales for our solutions business.

What advice do you have for ESCP applicants?

The application process at ECON consists of three case-based interviews. Therefore, I highly recommend practicing this interview format. On the one hand it is important to get used to the structured approach of problem solving. To exercise this approach I read books such as Case in Point by Mark Consentio and solved a lot of case studies. The website preplounge.com is also quite useful. On the other hand I solved case studies and conducted mock interviews together with other students also applying for consulting jobs – the direct feedback was especially valuable for my preparation.

E.ON is a company in the energy industry; thus, some content of the case study will likely be related to the energy sector. Although you do not have to be an energy expert to apply at ECON, I would recommend getting a basic understanding of the industry and the current challenges in the market.
