Guess-estimates and Market Sizing Questions
Market sizing questions are straightforward and should be solved within 10 minutes and 4-5 steps with 1 level of segmentation. You measure the existing market of an item in total units or total sales (Rs.) (it is important to clarify up front which one it is unless mentioned). In most market sizing cases, the interviewer has no clue of the exact solution – nor does he/she care. The emphasis is more on how you arrive at your conclusion (did you go off on a tangent? could you defend your assumptions?) rather than the conclusion itself. They are only testing your thought process.

Also, for market sizing questions, be prepared for adjustments at the end of the case – “What if the % of the population used was this? What is your most sensitive assumption?”

 Logical Reasoning and Brainteasers
Brainteasers are logic puzzles and/or riddles asked by the interviewers to test analytical and creative thinking process of the interviewee. Never give the answer right away. Take some time to think and then try finding a logical solution. The interviewer is most interested in your thought process and not in the final answer.
