The most common and critical mistakes are:

1) Not clarifying / asking the details of the business model in the beginning

2) Not clarifying / quantifying objectives in the beginning

3) Using common frameworks and not adapting them to the case specifics

4) Not digging deep into the root causes of a problem and switching to other parts of your framework

5) Getting some data and not applying it (i.e. you should compare with previous periods / benchmarks / breakdown further into segments)

6) Slow math / math with mistakes / not stating clearly what you are trying to calculate and why

7) Providing a strong conclusion having limited data

8) !!! spending a lot of time on cases, having no fit interview practice
