Description
In this course, we aim to provide you with a focused and efficient approach to preparing for data science interviews. We understand that your time is valuable, so we have carefully curated the content to cut out any unnecessary noise and provide you with the most relevant materials. Moving beyond theory, the course will dive into a wide range of practical data science interview questions. These questions have been carefully selected to represent the types of problems frequently encountered in real-world data science roles. By practicing these questions, you will develop the skills and intuition necessary to tackle similar problems during interviews.Throughout the course, we have filtered out any extraneous materials and focused solely on the core topics and questions that are most likely to come up in data science interviews. This approach will save you time and allow you to focus your efforts on what truly matters.Index:Missing values and how to handle them?
