Case studies are increasing there level of presence in the PIs these days just to make sure the interviewee is thinking in line with what the company wants, as a part of its team :)
What i can think of right now, so as to face Case Studies properly is to follow the 3 point pattern:
1. WHAT - is the situation; the issue; the problem - that is conveyed through the case study
2. WHY - is the issue; or the problem in this state - reasons
3. HOW - can it be faced; the steps to confront them, and get to a better situation; a solution - as the case demands..
Getting these 3 points clear will make the assessment of the same very clear, and simple.
Do share your thoughts on the same..
Loads of wishes and gratitude,
Kirtan..
