Welcome on my PrepLounge coaching profile! My name is Dennis and I'm happy to provide you with an overview of my coaching offering. Feel free to browse through the different sections of the profile to learn more about my background and experiences, the kind of coaching I focus on as well as details on my coaching approach. You can also find some free sample case interviews for you to practice with.

Having spent more than 7 years in a leading management consulting firm in Germany and the US, I have worn all sorts of different hats myself: being an applicant in the recruiting process of consulting firms, working first as a consultant and later as a manager in the day-to-day consulting business as well as serving as a recruiter interviewing and evaluating new candidates. I will use these experiences and insights to support you in achieving your personal goals.

In my free time, I enjoy literature (both classic and contemporary), hiking, playing guitar and I'm also a big sports fan.

Please feel free to just send me a message for questions or comments and I'm looking forward to getting to know you.

Are you looking to effectively prepare for the Roland Berger recruiting process?
=> You have come to the right address!

I have worked at RB for over 7 years, in various offices on 2 different continents, in both consulting and recruiting, with a personal journey from entry level consultant to project management. I'm deeply familiar with the company culture and the recruiting process to give you an edge in your preparation.

Are you looking to prepare for the recruiting process of other management consulting firms?
=> You have still come to the right address!

The Tier 1 and 2 consulting firms are all basically looking for candidates with similar profiles and qualities and are essentially competing for the same pool of applicants. While certain details may differ in the specific recruiting process from one consulting firm to the next, the general skill of solving case studies or convincing in a personal fit interview are universally applicable. My coaching approach will provide you with the tools and strategies to be successful at any recruiting process.

Interview Coaching

Dennis hat sich außergewöhnlich viel Zeit für mich genommen und mir sehr wertvolles, fundiertes Feedback gegeben

Coaching from Premium + Coaching

Organisation: We spoke about the needs for my upcoming consulting interview regarding layout and relevant materials Case: The case was immersive and it felt engaging in the sense that my knowledge was put to the test with relevancy to what my original needs were- it wasn't just a random case online but a more tailored approach which I found very useful. Case feedback: This is the most important part because we diagnosed the relevant issues, discussed them and importantly, how to solve those issues. I quite like the "homework" approach of doing drills to exercise the muscle per say. I found Dennis to be level headed, easy to understand and have good knowledge in general, which I found to be a motivation to carry on. Definitely recommend and having a follow-up meeting myself
