How do you stay current with the latest trends and advancements in data science, and can you give an example of how you have applied new techniques or technologies in your work?

Tell me about a time when you had to communicate complex technical findings to a non-technical audience. How did you ensure they understood the key takeaways?

In a machine learning project, how do you approach feature selection and ensure the model's performance is optimized? Can you provide an example from your past experience?

If you were given a large dataset with missing values and outliers, how would you preprocess the data before building a predictive model? Walk me through your thought process and the steps you would take.
