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 terms and provide examples of algorithms used in each category. Highlight the importance of choosing the right approach based on the problem at hand.

Example

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

2. Describe your experience with data pipelines. What tools have you used?

This question assesses your practical experience in managing data flows.

How to Answer

Discuss specific tools and technologies you have used, such as Apache Airflow or custom scripts, and explain how you ensured data integrity and efficiency.
