Other note the case study, but I want to provide much more feedback for those going through the process. Like others, the case study is a simply story of a company in needs of assistance. But, this is where the process goes wrong.
In the prompts, they specifically ask you to create a project plan to implement a sequence of initiatives. They want you to take into account some technical aspects of the plan. However, after receiving feedback, this is NOT what they want at all.
They want you to take the hand hold the clients. They want you to say: At this stage, I recognize that some stakeholders would be resistant to the change. Here is how I would help bring them along or ensure the project continues to move forward. Or, I would provide weekly reports to the executive team on all key decisions of the week, and seek input.
As a current consultant, this is what I do everyday, BUT that is not what the prompts ask you to do. The CEO made a comment that 60% of people fail the case study. And, now I know why. The case study doesn't ask the questions they want from you. They ask you to create a plan to organize initiatives, not a plan of action that addresses challenges that may emerge as you go through the process.
At every stage of the interview process, it was clear they want you to succeed with the one sheeters provided ahead of time. At this stage, I am not sure why, but they have asked the wrong question for the response they want.
I hope that folks read this and like this post, because I believe this will get you the job if you address change management challenges, rather than provide a detailed plan of implementation.
Or, I hope they change the questions so that they get the response they are seeking.
