In this section, we’ll review the various interview questions that might be asked during a Data Scientist interview at Kemper. The interview process will likely assess your technical skills, problem-solving abilities, and communication skills, particularly in how you present your analytical solutions and past projects. Be prepared to discuss your experience with data science methodologies, programming languages, and your approach to real-world business problems.

Machine Learning

1. Can you describe a machine learning project you have worked on? What was your role, and what were the outcomes?

This question aims to gauge your practical experience with machine learning projects. Focus on your specific contributions, the techniques you used, and the impact of the project on the organization.

How to Answer

Discuss the project’s objectives, the data you worked with, the models you implemented, and the results achieved. Highlight any challenges faced and how you overcame them.

Example

“I worked on a project to predict customer churn for an insurance product. My role involved data preprocessing, feature selection, and implementing a random forest model. The model improved our retention strategy, leading to a 15% reduction in churn over six months.”

2. What techniques would you use to handle imbalanced datasets?

This question tests your understanding of a common issue in data science.

How to Answer

Discuss techniques such as resampling methods, using different evaluation metrics, or applying algorithms that are robust to class imbalance.

Example

“To handle imbalanced datasets, I would consider using techniques like SMOTE for oversampling the minority class or undersampling the majority class. Additionally, I would use metrics like F1-score or AUC-ROC to evaluate model performance instead of accuracy.”

3. How do you select the right model for a given problem?

This question assesses your analytical thinking and understanding of model selection.

How to Answer

Explain your approach to understanding the problem, the data available, and the performance metrics that matter for the business context.

Example

“I start by analyzing the problem type—whether it’s classification or regression. Then, I evaluate the data characteristics, such as size and feature types. I typically begin with simpler models to establish a baseline and then explore more complex models based on performance metrics relevant to the business goals.”

4. Describe a time when you had to explain a complex model to a non-technical audience.

This question evaluates your communication skills, which are crucial for a data scientist.

How to Answer

Focus on how you simplified the technical details and used analogies or visual aids to convey your message.

Example

“I once presented a neural network model to our marketing team. I used visualizations to show how the model processed data and made predictions. I compared the model’s decision-making process to how a human might evaluate options, which helped them understand its functionality without getting lost in technical jargon.”

5. What is your experience with natural language processing (NLP)?

This question assesses your familiarity with NLP techniques, which may be relevant to the role.

How to Answer

Discuss any projects or applications where you utilized NLP, the tools you used, and the outcomes.

Example

“I worked on a sentiment analysis project where I used Python’s NLTK library to analyze customer feedback. By applying techniques like tokenization and sentiment scoring, we were able to identify key areas for product improvement, which directly influenced our development roadmap.”

Statistics & Probability

1. Explain the difference between Type I and Type II errors.

This question tests your foundational knowledge in statistics.

How to Answer

Clearly define both types of errors and provide context on their implications in decision-making.

Example

“A Type I error occurs when we reject a true null hypothesis, while a Type II error happens when we fail to reject a false null hypothesis. In a business context, a Type I error might mean incorrectly concluding that a new marketing strategy is effective, leading to unnecessary spending.”

2. How do you handle missing data in a dataset?

This question assesses your data preprocessing skills.

How to Answer

Discuss various strategies for dealing with missing data, including imputation methods and the impact of missing data on analysis.

Example

“I typically assess the extent of missing data first. For small amounts, I might use mean or median imputation. For larger gaps, I consider using predictive models to estimate missing values or even dropping those records if they are not critical to the analysis.”

3. What statistical methods do you use to validate your models?

This question evaluates your understanding of model validation techniques.

How to Answer

Mention techniques such as cross-validation, A/B testing, and performance metrics.

Example

“I use k-fold cross-validation to ensure my model generalizes well to unseen data. Additionally, I implement A/B testing in production to compare the performance of the new model against the existing one, using metrics like lift and conversion rates.”

4. Can you explain the concept of p-values?

This question tests your understanding of hypothesis testing.

How to Answer

Define p-values and their significance in statistical testing.

Example

“A p-value indicates the probability of observing the data, or something more extreme, if the null hypothesis is true. A low p-value suggests that we can reject the null hypothesis, indicating that our findings are statistically significant.”

5. How do you determine if a model is overfitting?

This question assesses your ability to evaluate model performance.

How to Answer

Discuss techniques for identifying overfitting, such as comparing training and validation performance.

Example

“I check the model’s performance on both training and validation datasets. If the training accuracy is significantly higher than the validation accuracy, it’s a sign of overfitting. I would then consider techniques like regularization or pruning to mitigate this issue.”
