SQL and Database Management

1. Can you explain the difference between INNER JOIN and LEFT JOIN in SQL?

Understanding the nuances of SQL joins is crucial for data retrieval tasks.

How to Answer

Discuss the definitions of both INNER JOIN and LEFT JOIN, emphasizing how they differ in terms of the data they return.

Example

"An INNER JOIN returns only the rows where there is a match in both tables, while a LEFT JOIN returns all rows from the left table and the matched rows from the right table. If there is no match, NULL values are returned for columns from the right table."

2. How would you write a SQL query to find the second maximum salary from a table?

This question tests your problem-solving skills and SQL proficiency.

How to Answer

Outline your approach to solving the problem, including any specific SQL functions you would use.

Example

"I would use a subquery to first find the maximum salary and then use that result to find the second maximum. The query would look something like: SELECT MAX(salary) FROM employees WHERE salary < (SELECT MAX(salary) FROM employees);"

3. What are window functions in SQL, and can you provide an example of how you would use one?

Window functions are essential for performing calculations across a set of table rows related to the current row.

How to Answer

Explain what window functions are and provide a specific use case.

Example

"Window functions allow you to perform calculations across a set of rows that are related to the current row. For example, I could use the ROW_NUMBER() function to assign a unique sequential integer to rows within a partition of a result set, which is useful for ranking employees by salary within their departments."

4. Describe a scenario where you had to optimize a slow-running SQL query. What steps did you take?

This question assesses your analytical skills and experience with performance tuning.

How to Answer

Discuss the specific steps you took to identify and resolve the performance issue.

Example

"I once encountered a slow-running query that was causing delays in reporting. I analyzed the execution plan, identified missing indexes, and added them. I also simplified the query by removing unnecessary joins, which improved the performance significantly."

Machine Learning and Data Analysis

5. Can you explain how a decision tree works?

This question tests your understanding of machine learning models.

How to Answer

Provide a brief overview of decision trees, including how they make decisions based on feature values.

Example

"A decision tree is a flowchart-like structure where each internal node represents a feature, each branch represents a decision rule, and each leaf node represents an outcome. It splits the data into subsets based on the value of the features, making it easy to interpret and visualize."

6. How would you estimate the number of Uber rides booked in India in a day?

This question evaluates your analytical thinking and ability to make estimations based on available data.

How to Answer

Outline the factors you would consider and the data points you would analyze to arrive at an estimate.

Example

"I would consider factors such as the population of major cities, the percentage of the population using ride-sharing services, average rides per user, and peak times for ride requests. By gathering data on these variables, I could create a model to estimate the total number of rides."

7. What techniques would you use to handle missing data in a dataset?

This question assesses your data cleaning and preprocessing skills.

How to Answer

Discuss various methods for dealing with missing data and when to use each.

Example

"I would first analyze the extent of the missing data. If it's minimal, I might use imputation techniques like mean or median substitution. For larger gaps, I might consider removing those records or using more advanced methods like predictive modeling to estimate the missing values."

8. Describe a time when you derived meaningful insights from a dataset. What was your approach?

This question allows you to showcase your analytical skills and ability to communicate findings.

How to Answer

Share a specific example, detailing your methodology and the impact of your insights.

Example

"In a previous role, I analyzed customer purchase data to identify trends in buying behavior. By segmenting the data and applying clustering techniques, I discovered a previously unnoticed customer segment that preferred eco-friendly products. This insight led to targeted marketing campaigns that increased sales by 20%."
