“I have extensive experience with Python, particularly in data manipulation using Pandas and data visualization with Matplotlib. In my last role, I used Python to automate data extraction processes, which saved the team several hours each week.”

4. Suppose you noticed a KPI for one of our ML models dipped sharply and then recovered over a span of an hour yesterday. Come up with some hypotheses about the cause. What would you do to investigate?

This question tests your analytical thinking and problem-solving skills.

How to Answer

Outline a structured approach to investigate the issue, including data analysis, stakeholder interviews, and reviewing system logs. Emphasize your ability to think critically and methodically.

Example

“I would start by analyzing the data around the time of the dip to identify any anomalies or patterns. I would also check for any changes in the model’s input data or external factors that could have influenced the KPI.

5. Discuss why you did your project the way you did.

This question allows you to showcase your decision-making process and project management skills.

How to Answer

Explain the rationale behind your project decisions, including any challenges you faced and how you overcame them. Highlight your ability to adapt and learn from experiences.

Example

“In my last project, I chose to implement a data warehouse solution because it allowed for better data integration and reporting capabilities.

How to Answer

Discuss the types of anomalies you would look for, such as duplicate entries or unusual patterns in user behavior. Provide a brief overview of the SQL queries you would use to investigate.

Example

“I would first check for duplicate user IDs and installations by running a query to count occurrences. Then, I would analyze the installation timestamps to identify any unusual spikes in activity. For example, I might use a query like SELECT user_id, COUNT(*) FROM installations GROUP BY user_id HAVING COUNT(*) > 1 to find duplicates.”

2. Write a Python script to get all combinations from a list of numbers.

This question tests your coding skills and understanding of algorithms.

How to Answer

Explain your thought process for solving the problem, including any libraries you would use. Provide a high-level overview of the script structure.

This question evaluates your understanding of data architecture and pipeline design.

How to Answer

Outline the steps you would take to design the pipeline, including data sources, transformation processes, and storage solutions. Emphasize your ability to create scalable and efficient systems.

Example

“I would start by identifying the data sources needed for the new feature, such as user interactions and external APIs. Next, I would design the ETL process to clean and transform the data before loading it into a data warehouse. Finally, I would ensure that the pipeline is scalable by using cloud-based solutions and monitoring tools to track performance.”

4. Can you explain Bayesian statistics and how it applies to business intelligence?

This question tests your knowledge of statistical methods relevant to the role.
