I believe that every applicant needs their individual approach to preparing for a successful consulting application, depending on your background and experience.
After baselining and usually a simulated interview, we can jointly decide, what's best for you:
Case basics: getting the basics of how to solve a case right, economic and strategic principles, what to definitely do - and what absolutely not to do; especially helpful for applicants with a more "exotic" background (such as myself, with an academic background in science)
Case experience: you got the basics but you lack training & experience - we'll build on my repertoire of different, real-life consulting cases to get you all track record you need to excel at your interview
Soft skills: what is your motivation to go into consulting - a question so simple, yet too many interviewees fail to answer it concisely. Finding your right answers to the softer questions in your interviews is important for getting your offer - just as much as getting your case right
