What The Heck does a consultant do?

Discover the nitty-gritty of a real
consultant's works


Hi, my name is Kim Tran. I’m a former McKinsey consultant and the founder of MConsultingPrep.
People often say “either you have it or you don’t”. There are certain innate capabilities that one must have in order to make it to management consulting.
I am here to testify that it is NOT true. I strongly believe that everything in life can be learned through a systematic approach and sound training. I have been in your shoes, I have felt your frustrations, and I know it is a tough process!
But together we can make it. Join me and 20,000+ other candidates around the world on the journey to not only conquer the consulting recruitment process but also to challenge your own limits!

" Wow! It is really an eye-opening critique, thank you so much! I truly appreciate that you took the time to look at my cover letter and gave so useful remarks. I will definitely focus more on the CV language and other weak points you mentioned.... Thank you very much, your service is worth every dime. "

Justina, Lithuania

" Practice tests from the McKinsey website give me a sense of how PST are like, but they do not tell me very much about how to ace them. This bugs me badly until I got the Full Package from you. You guys do a great job in breaking down the test into different question types. I was able to isolate specific skills and logics to train myself. That makes all the difference! Haven't taken the test yet, but I do feel much more prepared with your guides! "

Ryan, Yale University

" I'd like to thank you for your PST preparation materials. They were just excellent, I think I won't have passed my PST without them. Most importantly, they prepare you for the shock of facing so many charts and questions and dealing with them in such a short time. And I can say the actual exam felt much easier than your tests, which is great! So, you're doing a great job, very good value for money! "

Vadim Kotikov

" ... I am certain that the program is worth way more than what is listed and you and the team are actually doing us a favor by putting such a complete guide at a low cost. I want to extend my upmost gratitude to you Mr.Kim. You have not only helped but also inspired and motivated this young but driven candidate from a small town in Puerto Rico. You are a true leader sir!... "

Gustavo Andres

" I can't thank you enough for pointing out the necessity of tackling case interviews in three aspects: Intuition, Techniques, and Math. I tried LOMS of Victor Cheng but it seems to only tackle one part of the big picture. I knew something was missing but can't find out what it is. Now your E2E secrets package is the perfect answer for that. "
