💡 Model Answer

To fill null values in the salary column, I would typically use the column's mean or median, depending on the distribution. In Pandas, you can do: df['salary'].fillna(df['salary'].mean(), inplace=True). If the data is skewed, the median is safer. For a quick placeholder, you could also use a constant like 0 or a typical entry‑level salary.
