2. How would you optimize a slow-running SQL query?

Performance optimization is key in data analysis, especially when dealing with large datasets.

How to Answer

Discuss various strategies such as indexing, query restructuring, and analyzing execution plans.

3. Describe a complex SQL query you have written. What was its purpose?

This question assesses your practical experience with SQL.

How to Answer

Provide a specific example, detailing the query's complexity and its intended outcome.

Example

"I wrote a complex SQL query to analyze customer purchase patterns over the last year. It involved multiple JOINs across several tables, aggregating data to show total sales by customer segment and month. This helped the marketing team tailor their campaigns effectively."

4. What is ETL, and can you describe a process you have implemented?

ETL (Extract, Transform, Load) processes are essential for data integration.

How to Answer

Define ETL and describe a specific instance where you implemented it, focusing on the tools and methods used.

Example

"ETL stands for Extract, Transform, Load. I implemented an ETL process using SQL and Python to consolidate sales data from various sources into a centralized database. This involved extracting data from CSV files, transforming it to ensure consistency, and loading it into a SQL database for analysis."

Statistics and Data Analysis

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

Handling missing data is a common challenge in data analysis.

How to Answer

Discuss various methods such as imputation, deletion, or using algorithms that support missing values.

Machine Learning

1. What is the difference between supervised and unsupervised learning?

Understanding machine learning concepts is increasingly important for data analysts.

How to Answer

Define both types of learning and provide examples of each.

Example

"Supervised learning involves training a model on labeled data, where the outcome is known, such as predicting sales based on historical data. Unsupervised learning, on the other hand, deals with unlabeled data, aiming to find patterns or groupings, like customer segmentation."
