Many organizations use puzzles for testing their candidates on their problem-solving skills.

  Prepare to Face Case Studies Organizations use case studies as a means of evaluating candidates on how they approach real-life problems.

Case studies are the closest thing to the problems that you would be encountering in your role later on.

I have seen freshers struggle the most with this part of the data science interview process.

The tricky aspect of a case study is that it might not be directly related to data science.

For example, I got a case study around how to predict the number of black cars in Delhi NCR right now.

It’s a tricky one – but if you have a structured mindset – you’ll knock it out of the park!.Approaching a case study can appear hard since there is no fixed formula to solve them.

I highly recommend spending some time reading about the company’s mission, vision and core values.

Find out about their key achievements.

Try and find the data science set up that they have and what kind of projects they work on.

If possible, find out about the hierarchy of the organization and how the data science team fits into it.

Studying the organization and its structure will help you frame better questions for your interviewers.

This shows your enthusiasm and curiosity towards the organization and leaves your interviewers impressed.
