Q1: How would you handle real-time data streaming for analyzing user listening patterns?
Ans: I'd use platforms like Apache Kafka for real-time data ingestion. Using Python, I'd process this stream to identify real-time patterns and store aggregated data for further analysis.
Q2: Describe a situation where you had to use time series analysis to forecast a trend.
Ans: I analyzed monthly active users to forecast future growth. Using Python's statsmodels, I applied ARIMA modeling to the time series data and provided a forecast for the next six months.
Q3: How would you segment and analyze user behavior based on their music preferences?
Ans: I'd cluster users based on their listening history using unsupervised machine learning techniques like K-means clustering. This would help in creating personalized playlists or recommendations.
Q4: How do you handle missing or incomplete data in user listening logs?
Ans: I'd use imputation methods based on the nature of the missing data. For instance, if a user's listening time is missing, I might impute it based on their average listening time or use collaborative filtering methods to estimate it based on similar users.

📊 Excel Scenario Based Questions 👇👇
📈 Scenario 1:
Question: You're given a huge dataset of customer orders. How would you identify the top 5 customers by total sales?
Answer:
I would use a Pivot Table to summarize sales by customer. Then, I’d sort the sales column in descending order and filter the top 5 customers using the "Top 10 Filter" option in the Pivot Table.
🔄 Scenario 2:
Question: You find duplicate entries in your Excel sheet. How would you identify and remove them efficiently?
Answer:
I’d select the relevant data range, go to the Data tab, and use the Remove Duplicates feature. Before removing, I might highlight duplicates using Conditional Formatting for visual confirmation.
📆 Scenario 3:
Question: You need to calculate the number of working days between two dates excluding weekends and holidays. What function would you use?
Answer:
I would use the NETWORKDAYS() function.
Example:
📊 Scenario 4:
Question: You want to track monthly sales trends over time. How would you visualize this in Excel?
Answer:
I’d summarize the data in a Pivot Table by month, then insert a Line Chart or Column Chart to visualize trends clearly.
⚙️ Scenario 5:
Question: You need to apply the same formula across thousands of rows. What's the best way?
Answer:
I’d write the formula in the first cell and double-click the fill handle to auto-fill it down. Alternatively, I could use structured tables or dynamic arrays for efficiency.
