Interesting question!  
  
 The answer - BSchool would love you to bring a unique experience which can add value to the class. To give you an example, in case study based pedagogy they have cases from oil, infra, health, semiconductor, software, mining, social welfare and all such industries. When you bring working knowledge of that field - people would love your inputs!

The case studies are useless in most cases. Everything is imaginary

Not perfect but better than theoretical lectures!
