In this section, we’ll review the various interview questions that might be asked during a Data Analyst interview at Swiggy. The interview process will assess your technical skills in SQL, statistics, and problem-solving, as well as your ability to apply these skills to real-world business scenarios. Be prepared to demonstrate your analytical thinking and how you can leverage data to drive business decisions.

SQL and Data Manipulation

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

Understanding SQL joins is crucial for data manipulation and analysis.

How to Answer

Clearly define both types of joins and provide examples of when you would use each.

Example

“An INNER JOIN returns only the rows that have matching values in both tables, while a LEFT JOIN returns all rows from the left table and the matched rows from the right table. For instance, if I want to list all customers and their orders, I would use a LEFT JOIN to ensure I include customers who haven’t placed any orders.”

2. Write a SQL query to find the top 5 products by sales.

This question tests your ability to write efficient SQL queries.

How to Answer

Outline your thought process before writing the query, and ensure you mention any necessary functions or clauses.

Example

“I would use the SELECT statement with the SUM function to aggregate sales, followed by the ORDER BY clause to sort the results in descending order, and finally the LIMIT clause to restrict the output to the top 5 products.”

3. How would you handle missing data in a dataset?

Handling missing data is a common challenge in data analysis.

How to Answer

Discuss various strategies such as imputation, removal, or using algorithms that support missing values.

Example

“I would first analyze the extent of the missing data. If it’s minimal, I might choose to remove those records. For larger gaps, I could use imputation techniques, such as filling in the mean or median values, or even using predictive modeling to estimate the missing values.”

4. Explain the concept of window functions in SQL.

Window functions are essential for advanced data analysis.

How to Answer

Define window functions and explain their use cases, particularly in analytics.

Example

“Window functions allow us to perform calculations across a set of table 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 items.”

5. How do you optimize a slow-running SQL query?

Performance optimization is key in data analysis.

How to Answer

Discuss indexing, query structure, and analyzing execution plans.

Example

“I would start by examining the execution plan to identify bottlenecks. Then, I might add indexes to columns that are frequently used in WHERE clauses or JOIN conditions. Additionally, I would review the query structure to eliminate unnecessary subqueries or joins.”

Statistics and Probability

1. What is the Central Limit Theorem and why is it important?

Understanding statistical concepts is vital for data analysis.

How to Answer

Explain the theorem and its implications for sampling distributions.

Example

“The Central Limit Theorem states that the distribution of the sample means approaches a normal distribution as the sample size increases, regardless of the population's distribution. This is important because it allows us to make inferences about population parameters even when the population distribution is unknown.”

2. How would you conduct a hypothesis test?

Hypothesis testing is a fundamental statistical method.

How to Answer

Outline the steps involved in hypothesis testing, including formulating null and alternative hypotheses.

Example

“I would start by defining the null and alternative hypotheses. Then, I would select a significance level, collect data, and calculate the test statistic. Finally, I would compare the test statistic to the critical value to determine whether to reject the null hypothesis.”

3. Explain the difference between Type I and Type II errors.

Understanding errors in hypothesis testing is crucial.

How to Answer

Define both types of errors and provide examples.

Example

“A Type I error occurs when we reject a true null hypothesis, while a Type II error happens when we fail to reject a false null hypothesis. For instance, in a medical test, a Type I error would mean falsely diagnosing a disease, while a Type II error would mean missing a diagnosis.”

4. What is a p-value?

P-values are essential in hypothesis testing.

How to Answer

Define p-values and their significance in statistical tests.

Example

“A p-value indicates the probability of observing the test results under the null hypothesis. A low p-value suggests that the observed data is unlikely under the null hypothesis, leading us to consider rejecting it.”

5. How do you determine if a dataset is normally distributed?

Normality is a key assumption in many statistical tests.

How to Answer

Discuss methods such as visual inspection and statistical tests.

Example

“I would use visual methods like histograms or Q-Q plots to assess normality. Additionally, I could apply statistical tests like the Shapiro-Wilk test to formally test for normality.”

Business and Problem Solving

1. How would you approach a business problem where sales have dropped?

This question assesses your analytical and problem-solving skills.

How to Answer

Outline a structured approach to diagnosing the issue.

Example

“I would start by analyzing sales data to identify trends and patterns. Next, I would segment the data by customer demographics, product categories, and time periods to pinpoint the cause. Finally, I would propose actionable strategies based on my findings.”

2. Describe a time when you used data to influence a business decision.

This question evaluates your practical experience.

How to Answer

Use the STAR method (Situation, Task, Action, Result) to structure your response.

Example

“In my previous role, I noticed a decline in customer retention rates. I analyzed customer feedback and purchase patterns, which revealed that a lack of engagement was the issue. I presented my findings to management, and we implemented a targeted marketing campaign that increased retention by 15%.”

3. What metrics would you track to measure the success of a new feature?

Understanding key performance indicators (KPIs) is essential.

How to Answer

Discuss relevant metrics and their importance.

Example

“I would track metrics such as user adoption rate, engagement levels, and conversion rates. Additionally, I would monitor customer feedback and retention rates to assess the feature's overall impact on user satisfaction and business goals.”

4. How do you prioritize tasks when working on multiple projects?

Time management and prioritization are key skills for a data analyst.

How to Answer

Explain your approach to prioritization based on urgency and impact.

Example

“I prioritize tasks by assessing their deadlines and potential impact on the business. I use tools like project management software to keep track of progress and ensure that I allocate my time effectively to meet all project requirements.”

5. How would you estimate the number of orders Swiggy receives in a day?

This question tests your guesstimation and analytical thinking.

How to Answer

Outline a logical approach to making an estimation.

Example

“I would start by considering the population of the cities Swiggy operates in and the average number of orders per user. I could estimate the number of active users and multiply that by the average orders per user per day, adjusting for factors like peak times and promotions.”
