Tomas is the founder of Case Studies Plus. He worked as a management consultant at McKinsey & Company for four years in London and New York and has first hand knowledge of the consulting application process having been involved in the interview process whilst at McKinsey.
When preparing for management consulting interviews, Tomas noticed the lack of high-quality preparation materials which were tailored to the case study formats at McKinsey, Bain and BCG.
Alongside other experts with inside knowledge of the application processes and case study frameworks, he created Case Studies Plus to deliver applicants real-world case studies to increase their chances of success during the case study interview.
