That is why you need to have a clear understanding of the product that needs to be built to ensure that you can line up the work you do and can in fact apply it in the item.

Practice Makes Perfect: Mock Data Science Interviews

The recruiters look for whether you are able to take the context that's over there in the company side and can in fact convert that into a trouble that can be addressed utilizing data science. Item sense describes your understanding of the product all at once. It's not about fixing problems and getting embeded the technological details rather it is concerning having a clear understanding of the context.

You should be able to connect your mind and understanding of the problem to the partners you are dealing with. Analytical ability does not suggest that you understand what the issue is.
