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.

Coaching from Premium + Coaching
The coaching session with Dennis was very exciting. The insights into his project experience and his career in consulting were extremely valuable to me and gave me a much clearer picture of my specific requirements. I found it particularly helpful that his recommendations were very specific and clearly tailored to my current situation and next career steps. The session opened up new perspectives for my further preparation, and I can highly recommend this type of coaching to anyone facing similar decisions.

Interview Coaching
Dennis ist unglaublich kompetent und bringt einiges an Erfahrung mit, was man ihm während der Coaching-Session sofort anmerkt. Außerdem lässt er sich während des Coachings viel Zeit, um jeden Punkt ausführlich zu besprechen und stellt sicher, dass es keine Unklarheiten gibt. Ich kann ihn besten Gewissens weiterempfehlen.
