Motivation and background

Dr. "Jack" Jörg Leib

A passionate consultant

Becoming a top management consultant had been a professional career goal early on, and has remained my passion to this day. I assist my clients worldwide with their business — and sometimes personal — transformation journeys and enjoy consulting work, which includes a wide range of activities such as technical analyses, effective presentations and purposeful client communications.

My consulting background:
McKinsey and others

I established my consulting expertise over a number of consulting-related experiences and activities. Prior to serving as an independent management advisor, I worked for five years as a consultant and project manager for the world’s leading management consulting firm, McKinsey & Company. As a focus, I supported strategy projects in the raw materials industries and served clients in banking and mechanical engineering. These consulting projects have led me to America, Asia and Europe, covering both developing as well as industrialized countries, and I indeed have some “war stories” to tell…

Already prior to joining McKinsey I had researched the industry intensely. Among other activities, I did internships at McKinsey’s competitor Roland Berger, in “Big Four” firm Ernst & Young (EY)’s transaction advisory services unit and at a medium-sized consulting firm. Furthermore, I have interviewed with virtually all leading strategy consulting firms as well as some medium-sized consultancies. I have attended many consulting firms’ recruiting workshops (including several “top events”). During this process, I have developed highly effective application and interview strategies. I was also selected as one of 20 finalists from 2000 applicants for McKinsey’s “CEO of the Future” contest to solve and present a consulting case study to a panel of German stock exchange (DAX) company board members.

Moreover, I maintain a strong network of consultants who work for various firms and contribute their knowledge to YOUinConsulting.

Before becoming a management consultant, I completed a PhD at Imperial College London on the economics of climate change. I finished my studies in economics at the universities of Heidelberg, Jyväskylä (Finland) and Bonn as best in class.

Why YOUinConsulting?

Again and again, I have been asked for advice on (consulting) career decisions. Many people share the dream of becoming a management consultant and perhaps even starting their career at one of the world’s leading consulting firms. Others have already made the leap into consulting and now find themselves confronted with the recurring challenges that consulting business and its institutions regularly present.

I view it as a priority to empower these people to make the best career decisions, then guiding them towards career success. However, I found that the commonly available glossy career magazines, sponsored recruiting events, anonymous internet forums (and so forth) do not truly serve the purpose of differentiated opinion-forming and optimal career preparation.

I decided to satisfy this vital need for information through YOUinConsulting: For people who aspire to (or have already started) a career as a management consultant and want to shape it successfully, I developed Youinconsulting as an independent institution. It provides unprecedented consulting insider knowledge on the entire consulting life cycle – transparently, authentically, personally, and in a structured, didactic and entertaining form: entry, rise and exit!

Press and partners

Making YOUinConsulting and the insider knowledge it provides on the consulting industry more widely-known is a matter close to my heart. Therefore, I am generally available to contribute to industry reports, interviews, (online) panel discussions, etc., and to write high-quality articles for (online) news magazines, related blogs, etc. I create high-quality content and write all my articles personally (without a ghost writer). In addition, I am featured on the YOUinConsulting YouTube channel, showcasing my wide array of creative expression.
