The real problem
Knowing SQL syntax is not the same as being able to use SQL.
Tutorials can make SQL look easy. The difficulty starts when you're given a real dataset and a vague business question.
?
"Which JOIN should I use here?"You know JOINs exist, but choosing the right one still feels confusing.
?
"Should this be a subquery or a CTE?"You remember syntax, but structuring the solution is harder.
?
"How do I turn a business question into SQL?"This is the gap most tutorial-only learning never fully closes.
?
"What do I actually show in an interview?"A certificate alone is much weaker than a project you can explain.
This bootcamp is built to close that gap.
You won't just learn what SQL commands do. You'll practise when to use them, why they matter and how they help answer realistic business questions.

HR Analytics Using SQL
Work on a realistic Human Resources Analytics scenario and use SQL to investigate patterns, answer business questions and generate insights.
Why are employees leaving?
Is salary related to attrition?
How do performance and tenure vary across teams?
What department-level trends should HR investigate?
SELECT department, COUNT(*) AS employees, AVG(salary) AS avg_salary, AVG( CASE WHEN attrition = 'Yes' THEN 1 ELSE 0 END ) AS attrition_rate FROM employees GROUP BY department ORDER BY attrition_rate DESC;
