Four passes at the same skill, shortest first: the seven-minute method, a four-step alternative, then two firm-style walkthroughs with the interviewer grading the structure.
Every video plays through YouTube’s official embed player and belongs to the channel named on its row. Work down the list. The order is the curriculum.
EasyHacking the Case Interview
The shortest honest route into market sizing: the structure, the assumptions, and the difference between TAM, SAM, and SOM. Seven minutes that make every longer sizing video easier to follow.
EasyMissAngieLu
A four-step method for sizing anything, demonstrated on the croissants sold in Paris with an issue tree and openly stated assumptions. A good second angle if the formula-first approach has not clicked yet.
MediumManagement Consulted
A step-by-step sizing walkthrough in the McKinsey manner, from the first clarifying question to the sanity check at the end. Note how every assumption is said out loud before it is used.
MediumManagement Consulted
A Bain-style sizing framework built live, with the interviewer assessing the framework itself at the end. Useful for seeing how much of the grade sits in the structure rather than the arithmetic.
Put the patterns to work while they are fresh. The playlist is the input. The practice floor is where it becomes a skill.
I am your interviewer here. I run cases with you, drill your math, and tell you plainly which part of your game needs work. Ask me something, or press Hear it and I will introduce myself out loud in your device voice. The studio voice connects at launch.
He answers from the guide's own content and names the stage it lives in. He does not invent firm facts. On member accounts he remembers your year, school, progress, and scores, and you can see and clear what he remembers.
