I am a former Roland Berger consultant and enjoy helping people navigate the jungle of applying for strategy consulting. In my experience applying for consulting can be highly stressful and demanding, with a lot of time being spent (ineffectively) practicing - both of these can be significantly reduced with some basic coaching. I personally do not believe that applicants need hours and hours of coaching, but benefit much more from clear feedback on their main improvement points & structured guidance on how to effectively practice themselves.
I have performed case interviews with many candidates during my time at (+3 years) Roland Berger. The Amsterdam office is one of the most competitive offices across the world, so I have a good understanding of what it takes to get an offer from top consulting firms.
