How to Answer

Discuss a specific project, focusing on the problem you were solving, the data you used, and the technologies that were instrumental in your approach.

Example

“In my last role, I worked on a customer segmentation project where I utilized Python for data cleaning and analysis, and SQL for querying our database. I chose these technologies because they allowed for efficient data manipulation and were well-suited for the large datasets we were handling.”

2. Describe a time you had to clean and preprocess a dataset. What steps did you take?

Data cleaning is a crucial part of a data scientist's role, and Wpromote will want to know your methodology.

How to Answer

Outline the specific steps you took to clean the data, including handling missing values, outliers, and any transformations you performed.

Then, I used imputation techniques for missing values and standardized the formats of categorical variables to ensure consistency across the dataset.”

Problem-Solving

3. How would you approach a situation where your model is underperforming?

Understanding how to troubleshoot and improve models is essential for a data scientist.

How to Answer

Discuss your systematic approach to diagnosing the problem, including evaluating data quality, feature selection, and model parameters.

Example
