Cummins Inc. Machine Learning Engineer Interview Questions

In this section, we’ll review the various interview questions that might be asked during a Machine Learning Engineer interview at Cummins Inc. The interview process will likely assess your technical skills in algorithms, machine learning, and programming, as well as your ability to work collaboratively in a team environment. Be prepared to discuss your past experiences and how they relate to the role.

Technical Skills

1. Can you explain the difference between supervised and unsupervised learning?

Understanding the fundamental concepts of machine learning is crucial for this role.

How to Answer

Clearly define both supervised and unsupervised learning, providing examples of each. Highlight the scenarios in which you would use one over the other.

Example

“Supervised learning involves training a model on labeled data, where the outcome is known, such as predicting house prices based on features like size and location. In contrast, unsupervised learning deals with unlabeled data, aiming to find hidden patterns, like clustering customers based on purchasing behavior.”

2. What algorithms would you use for a regression problem?

This question tests your knowledge of algorithms relevant to machine learning tasks.

How to Answer

Discuss various regression algorithms, such as linear regression, decision trees, and support vector regression, and explain when you would use each.

Example

“For a regression problem, I would consider using linear regression for its simplicity and interpretability. If the relationship is non-linear, I might opt for decision trees or random forests, as they can capture complex patterns without requiring extensive feature engineering.”

3. How do you handle overfitting in a machine learning model?

Overfitting is a common issue in machine learning, and your approach to it is critical.

How to Answer

Explain techniques such as cross-validation, regularization, and pruning that can help mitigate overfitting.
