What Is the Best Consulting Firm for Me?

Every consulting firm is unique. If you are interested in working in consulting, the available options include working for the typical strategy consultancies , more specialized boutique consulting firms, or for the so-called inhouse consultancies which are basically internal consulting firms of big companies. The big players in strategy consulting know how to set the tone by means of branding, demanding projects, internationality, and last but not least through attractive salaries. Boutique consultancies have the advantage that consultants may work in their favorite field in order to evolve into specialists. Inhouse consultancies are becoming more and more important for the job market, since employees are looking for more promising work-life-balance properties in their employers. Moreover, you'll be able to do your own networking in a big firm, and therefore lay a solid foundation for the transition into the later stages of your career.

What Are Necessary Skills for Me as a Consultant?

You'll have to bring certain abilities to the table, but it's about more than what's on your resume. Despite an excellent academic education, your future employer will also look for working experience, especially if acquired abroad. Particularly if you studied business/economics, you'll be expected to have at least two internships on your record when being interviewed.

Do I Need an MBA to Apply for a Job in Consulting?

While an MBA can be beneficial, it's not a strict requirement to apply for a consulting job. Consulting firms often seek candidates with diverse educational backgrounds, including natural sciences, medicine, and pharmacy. They highly value organized and analytical working behavior. Beyond educational qualifications, firms also emphasize soft skills such as communication abilities, self-confidence, and analytical skills. Even without significant practical experience, if you demonstrate these qualities, you could potentially be considered for consulting roles. Some firms may also offer workshops and mini-MBA programs to further develop your skills once hired.

What Are the Benefits While Working as a Consultant?

Working as a consultant offers several benefits. While the role often requires long working hours, especially for those starting their careers, it compensates with high salaries. Additionally, the experience you gain as a consultant can lead to promising career advancements and opportunities for personal development, extending beyond the realm of consulting. Many consultants leverage their experience to transition into roles in large industrial companies, smaller boutique consultancies, or startups, which can offer diverse career paths.

Strategic Growth in Renewable Energy Technologies

Our Energy Infrastructure Solutions (EIS) business is growing rapidly. As one of our key business areas at E.ON, the EIS business is shaping the energy transition of cities and industries.To capture the massive growth potential, especially given the acceleration due to municipal heat planning, we identified early on that the EIS business required a clearly defined Renewable Energy Solutions (RES) strategy to ensure green electricity supply for our customers.

Accelerating E.ON’s Grid Expansion for Renewables

The political ambition towards a rapid energy transition has increased sharply in recent years. Namely, the German government passed the "Easter Package" which effectively quadrupled the required expansion speed for renewable energies. After this announcement, another ECON project showed that the distribution grid will be the backbone of this transition and needs to be expanded much faster than previously planned. Therefore, the aim of Project Bob was to identify ways to "build better" and ensure that E.ON's distribution grid is expanded fast enough to make the swift transition to renewables possible.

E.ON’s IT Transformation

In an era where the energy sector is rapidly digitalizing to keep up with growing demands and growth ambitions, E.ONs journey towards a fully digital company has already seen significant strides with cloud migration and data center closures. Now the Digital Technology teams across the E.ON group need to be enabled to elevate their value contribution through innovation, speed to market, and quality. This requires us to ensure that E.ON's IT is “fit-for-future” and augmented with the “state-of-the-art” technologies, capabilities and methodologies.
