Examples in SQL:
1. Create:
Adding new records to a table.
INSERT INTO students (id, name, age)
VALUES (1, 'John Doe', 20);
2. Read:
Retrieving data from a table.
SELECT * FROM students;
3. Update:
Modifying existing records.
UPDATE students
SET age = 21
WHERE id = 1;
4. Delete:
Removing records.
DELETE FROM students
WHERE id = 1;A step-by-step guide to land a job as a data analyst

Exploratory Data Analysis
When I started Data Analysis:
• I didnt understand Star Schema
• I didn’t know PowerBi
• I barely knew Excel
• I didn’t know DAX
• I didn’t know SQL
2 years later:
• I can build Data Models for any business
• I know excel to produce any report
• I can easily data with SQL
• I know PowerBi inside out
• I love DAX
I love data.
Next time you’re asked for data…
Try to learn the WHY.
What’s the business problem this solves.
Why do they think this data will solve it.
You’ll nearly always be able to help more than they realised.

Step-by-Step Guide to Land a Data Analyst Job ✅📈
Landing your first data analyst job might feel like climbing a mountain, but with the right steps, it’s absolutely achievable! Here are 11 actionable tips to simplify the journey and make it feel like less of a grind.
1. Master SQL
SQL is the bread and butter of data analytics. Start with basic queries like SELECT, WHERE, and JOIN, then move on to more advanced topics such as subqueries, window functions, and performance optimization. Knowing how to manipulate and retrieve data effectively is essential.
2. Next, Learn a BI Tool
Data visualization is critical to communicating insights. Get familiar with at least one popular Business Intelligence (BI) tool, like Power BI or Tableau. Master how to create dashboards and meaningful visualizations that tell the story behind the numbers.
3. Drink Lots of Tea or Coffee (for Focus)
Staying sharp while learning these tools and skills takes focus. Whatever keeps you energized—lean into it! The data world moves fast, so staying alert and ready is key.
4. Tackle Relevant Data Projects
Hands-on experience is what sets you apart. Start with personal projects or even freelance opportunities to practice real-world data analysis. From cleaning data sets to building dashboards, showcase how you approach problems and present solutions.
5. Create a Relevant Data Portfolio
Your portfolio is your proof of work. Include your SQL scripts, dashboards, case studies, and any insights derived from your data projects. Platforms like GitHub or Tableau Public are great for displaying your work.
6. Focus on Actionable Data Insights
It's not enough to just analyze data. Always aim to derive actionable insights that can drive business decisions. Ask yourself: "How can this data improve outcomes?"—and make sure to communicate that clearly.
7. Remember Imposter Syndrome is Normal
If you feel like you don’t belong, you’re not alone. Imposter syndrome is common, but what matters is that you push through it. Confidence builds as you gain more experience and knowledge.
8. Prove You’re a Problem-Solver (important)
Employers want to know if you can handle real-world data problems. Find ways to show off your critical thinking and ability to solve complex problems, whether it’s through personal projects or during interviews.
9. Develop Compelling Data Visualization Stories
Telling a story with data is a skill. Build a narrative around the data you analyze. Why does this insight matter? How can it be used to make better decisions? Great visuals plus a compelling story equal impact.
10. Engage with LinkedIn Posts from Fellow Analysts (optional)
Networking is vital in any field. Actively engage in conversations on LinkedIn—comment on posts, share your insights, and build relationships with others in the field. Visibility on professional platforms can lead to job opportunities.
11. Illustrate Your Analytical Impact with Metrics & KPIs
Show that your work delivers results. In your portfolio or resume, highlight specific metrics and key performance indicators (KPIs) you’ve influenced. This makes your value clear to potential employers.
BONUS TIP: Share Your Career Story & Insights via LinkedIn Posts. Let people know how you’re progressing, what you’ve learned, and what challenges you’ve overcome. Posting regularly helps position you as an aspiring data analyst who is active in the field.

Myntra interview questions for Data Analyst 2024.
1. You have a dataset with missing values. How would you use a combination of Pandas and NumPy to fill missing values based on the mean of the column?
2. How would you create a new column in a Pandas DataFrame by normalizing an existing numeric column using NumPy’s np.min() and np.max()?
3. Explain how to group a Pandas DataFrame by one column and apply a NumPy function, like np.std() (standard deviation), to each group.
4. How can you convert a time-series column in a Pandas DataFrame to NumPy’s datetime format for faster time-based calculations?
5. How would you identify and remove outliers from a Pandas DataFrame using NumPy’s Z-score method (scipy.stats.zscore)?
6. How would you use NumPy’s percentile() function to calculate specific quantiles for a numeric column in a Pandas DataFrame?
7. How would you use NumPy's polyfit() function to perform linear regression on a dataset stored in a Pandas DataFrame?
8. How can you use a combination of Pandas and NumPy to transform categorical data into dummy variables (one-hot encoding)?
9. How would you use both Pandas and NumPy to split a dataset into training and testing sets based on a random seed?
10. How can you apply NumPy's vectorize() function on a Pandas Series for better performance?
11. How would you optimize a Pandas DataFrame containing millions of rows by converting columns to NumPy arrays? Explain the benefits in terms of memory and speed.
12. How can you perform complex mathematical operations, such as matrix multiplication, using NumPy on a subset of a Pandas DataFrame?
13. Explain how you can use np.select() to perform conditional column operations in a Pandas DataFrame.
14. How can you handle time series data in Pandas and use NumPy to perform statistical analysis like rolling variance or covariance?
15. How can you integrate NumPy's random module (np.random) to generate random numbers and add them as a new column in a Pandas DataFrame?
16. Explain how you would use Pandas' applymap() function combined with NumPy’s vectorized operations to transform all elements in a DataFrame.
17. How can you apply mathematical transformations (e.g., square root, logarithm) from NumPy to specific columns in a Pandas DataFrame?
18. How would you efficiently perform element-wise operations between a Pandas DataFrame and a NumPy array of different dimensions?
19. How can you use NumPy functions like np.linalg.inv() or np.linalg.det() for linear algebra operations on numeric columns of a Pandas DataFrame?
20. Explain how you would compute the covariance matrix between multiple numeric columns of a DataFrame using NumPy.
21. What are the key differences between a Pandas DataFrame and a NumPy array? When would you use one over the other?
22. How can you convert a NumPy array into a Pandas DataFrame, and vice versa? Provide an example.
