How do you go about preparing data?

How to Proceed:

One of the most important phases in big data projects is data preparation. At least one question based on data preparation might be asked during a big data interview. The interviewer wants to know what processes or safety measures you use when preparing your data, which is why he asks you this question.

As you are already aware, data preparation is vital to obtain the appropriate data, which can then be utilized for modeling. This is the message you should provide to the interviewer. Additionally, be sure to highlight the kind of model you'll be using and the factors that went into your decision. In addition, you should go through key terms for data preparation such as converting variables, outlier values, and unstructured data.
