Python Interview Questions for data analyst interview
Question 1: Find the top 5 dates when the percentage change in Company A's stock price was the highest.
Question 2: Calculate the annualized volatility of Company B's stock price. (Hint: Annualized volatility is the standard deviation of daily returns multiplied by the square root of the number of trading days in a year.)
Question 3: Identify the longest streaks of consecutive days when the stock price of Company A was either increasing or decreasing continuously.
Question 4: Create a new column that represents the cumulative returns of Company A's stock price over the year.
Question 5: Calculate the 7-day rolling average of both Company A's and Company B's stock prices and find the date when the two rolling averages were closest to each other.
Question 6: Create a new DataFrame that contains only the dates when Company A's stock price was above its 50-day moving average, and Company B's stock price was below its 50-day moving average

🔍 Real-World Data Analyst Tasks & How to Solve Them
As a Data Analyst, your job isn’t just about writing SQL queries or making dashboards—it’s about solving business problems using data. Let’s explore some common real-world tasks and how you can handle them like a pro!
📌 Task 1: Cleaning Messy Data
Before analyzing data, you need to remove duplicates, handle missing values, and standardize formats.
✅ Solution (Using Pandas in Python):
import pandas as pd
df = pd.read_csv('sales_data.csv')
df.drop_duplicates(inplace=True) # Remove duplicate rows
df.fillna(0, inplace=True) # Fill missing values with 0
print(df.head())SELECT MONTH(SaleDate) AS Month, SUM(Quantity * Price) AS Total_Revenue
FROM Sales
GROUP BY MONTH(SaleDate)
ORDER BY Total_Revenue DESC;51 830

Importance of AI in Data Analytics
AI is transforming the way data is analyzed and insights are generated. Here's how AI adds value in data analytics:
1. Automated Data Cleaning
AI helps in detecting anomalies, missing values, and outliers automatically, improving data quality and saving analysts hours of manual work.
2. Faster & Smarter Decision Making
AI models can process massive datasets in seconds and suggest actionable insights, enabling real-time decision-making.
3. Predictive Analytics
AI enables forecasting future trends and behaviors using machine learning models (e.g., sales predictions, churn forecasting).
4. Natural Language Processing (NLP)
AI can analyze unstructured data like reviews, feedback, or comments using sentiment analysis, keyword extraction, and topic modeling.
5. Pattern Recognition
AI uncovers hidden patterns, correlations, and clusters in data that traditional analysis may miss.
6. Personalization & Recommendation
AI algorithms power recommendation systems (like on Netflix, Amazon) that personalize user experiences based on behavioral data.
7. Data Visualization Enhancement
AI auto-generates dashboards, chooses best chart types, and highlights key anomalies or insights without manual intervention.
8. Fraud Detection & Risk Analysis
AI models detect fraud and mitigate risks in real-time using anomaly detection and classification techniques.
9. Chatbots & Virtual Analysts
AI-powered tools like ChatGPT allow users to interact with data using natural language, removing the need for technical skills.
10. Operational Efficiency
AI automates repetitive tasks like report generation, data transformation, and alerts—freeing analysts to focus on strategy.

Data analytics is not about the the tools you master but about the people you influence.
I see many debates around the best tools such as:
- Excel vs SQL
- Python vs R
- Tableau vs PowerBI
- ChatGPT vs no ChatGPT
The truth is that business doesn't care about how you come up with your insights.
All business cares about is:
- the story line
- how well they can understand it
- your communication style
- the overall feeling after a presentation
These make the difference in being perceived as a great data analyst...
not the tools you may or may not master 😅
