I am a former BCG Principal with 6 years of experience in Consulting who just recently left the company (January, 2025). I have worked on 20+ live cases across Europe, Middle East and the US. Prior to leaving BCG, I spent 6 months working from their New York office. Before joining BCG, I worked for 3 years in Investment Banking at Deutsche Bank.

During my time at BCG, I have been a Senior Interviewer, conducting more than 300 real recruiting interviews and actively shaping the talent pool by being a first round interviewer who independently decides who advances into the second round. Additionally, I have been a mentor to a pool of younger colleagues from my office and practice area that I have advised on their personal development and future path within the company.

In a nutshell: I have profound experience of the Consulting interview process and what it takes to successfully get in and thrive on the job. I have always had a passion for helping others to reach their full potential and goals. I would be more than happy to help you achieve yours, too.

I am here to make you succeed in your interview process and beyond. The reality is that the Consulting recruiting process is highly competitive and being smart alone is not going to be sufficient. Due to years of being an MBB consultant myself and having interviewed countless candidates along the way, I know exactly where to focus and will adjust my coaching flexibly to your profile.

How we will work together

Fully tailored: Each candidate is different and has unique strengths and areas for development. I will be quick in understanding yours and adjusting our approach, no one-size fits all solutions here!
Full availability: You will receive my personal mobile number for direct interaction, in case you have follow-up or last-minute questions prior to your interviews
Fun: While this is a very important step for you, it is important not to forget to enjoy yourself while preparing and interviewing. I have seen lots of candidates that were too tense to unlock their full potential. I will help you bring the ease back ?

What support you can expect

One-stop shop: I am here to help you throughout the entire process. Apart from direct interview preparation, I am happy to review your application materials and support you throughout your first steps within the Consultancy once you have secured that offer.

If you want to bring MBB interview prep to the next level and excel your interview- Sebastian is your go-to through his tailored approach. He created a comprehensive narrative for my upcoming BCG interview by diving deep into my background and needs. Also, he walked me through multiple mock interviews by taking on the role of different interviewer archetypes. In addition, he increased my confidence in conducting interviews in German by refining my communication structure and storyline through repetition in a very short period. From a general point of view, Sebastian was fantastic to work with, always giving constructive, direct feedback and being supportive at all times. Therefore, I cannot recommend Sebastian enough in the MBB preparation journey, especially for BCG.

Interview Coaching

If you are looking for somebody that can get you into MBB, look no further. I have been prepping for a while now, but Sebastian’s coaching has by far been the most insightful, structured and helpful. Given the fact that he has been an interviewer himself, he knows exactly what Consultancies are looking for in a candidate and what they will ask and expect from a good candidate. Through his coaching, I was able to excel both in the personal fit and in the case part of the interview, ultimately helping me to secure full-time offers. For the personal fit part, Sebastian helped me to craft a consistent narrative around my profile that withstood all detailed questions from the interviewers and made me stand out from the pack. For the case part, Sebastian tailored his approach and case style to the companies that I was interviewing with and provided hands-on, granular feedback. By the time I got to the real interviews, I was 100% certain that could handle them.

Coaching from Premium + Coaching

I’ve had multiple coaching sessions on PrepLounge with various highly skilled coaches, but I cannot recommend Sebastian enough—he truly stands out. From the very start, Sebastian took the time to understand my specific situation through an initial touchpoint, which allowed him to tailor the coaching sessions perfectly to my needs—both for PEI preparation and case solving. I initially believed I had a solid grasp of the PEI component, but Sebastian elevated my performance to a whole new level. By the time I sat for my actual interviews, the PEI felt like a walk in the park. On the case side, he quickly identified key improvement areas, provided highly actionable insights, and worked with me through a structured rinse-and-repeat approach that significantly boosted my confidence and performance. With a tight timeline between receiving my interview invitation and my first-round interview, Sebastian went above and beyond to accommodate my schedule and maximize every session. His dedication, expertise, and ability to fine-tune my approach made all the difference—it simply would not have been possible to pass without his guidance. For anyone looking for top-tier coaching that delivers real results, Sebastian gets my highest recommendation. If you want to walk into your consulting interviews feeling fully prepared, he's the coach you need.
