To whom it may concern
It’s hard for me, a fresh graduator with endless enthusiasm in the Enterprise Management, to seek another niche without McKinsey, who is the locomotive of this field. From the very beginning, I had understood the importance of efficient management consultation. Frankly, the professional of McKinsey is a kind of spring of my consistent pursuing.
Staff of McKinsey comes from every corner worldwide, though they enjoy totally different background and unique personality; they still work diligent without any grudge for the common destination. The reliability and assistance among the McKinsey members do move me. For this reason, I am very eager to be a member of this family and make my dream come true.
During my four-year education in the university, I’ve equipped myself with all necessary professional knowledge, not only my major but also other courses which might be helpful in my way to become a qualified consultant in the near future. After studying Adam Smith’s Division of Labor and Taylor’s Scientific Management, the broad outlook is forced. Also, the importance of mathematics is realized by me as well, especially Mathematical Modeling, it will be very useful in my future work. Whenever I faced a difficulty, I always work with full confidence and never give up all the way.
Once there is a person, who said people should do what correct they believe. To me, becoming a member of McKinsey is just this issue. The bright future is just there; sincerely wish that the I can have the honor to work with all the McKinsey crew hand in hand
