Sample Questions
A cross-section of questions from across all difficulty levels and technologies. Each question includes a short hint to point you in the right direction without giving the answer away.
Q1. What is the difference between an abstract class and an interface in Java? When would you use one over the other?
Hint: Think about multiple inheritance, default methods (Java 8+), and whether the class shares a common behaviour or a common contract.
Q2. What is the difference between state and props in React? Can a child component modify its own props?
Hint: Props flow down from parent to child and are read-only. State is local to a component and managed with useState or a class component's this.state.
Q3. What is the difference between INNER JOIN, LEFT JOIN, and FULL OUTER JOIN? Write an example query for each.
Hint: Focus on which rows are returned when there is no match in one of the tables — that is the key distinction.
Q4. A Lambda function is timing out when reading from an RDS instance inside a VPC. Walk through the steps you would take to diagnose and fix the issue.
Hint: Check security group rules, Lambda VPC configuration, subnet routing, and whether the function has the right IAM permissions for VPC networking.
Q5. What are Python decorators? Write a simple decorator that logs the name and execution time of any function it wraps.
Hint: A decorator is a function that takes another function and extends its behaviour without modifying it directly. Use functools.wraps to preserve metadata.
Q6. Describe a situation where you had to learn a new technology under a tight deadline. How did you approach it and what was the outcome?
Hint: Use the STAR method — Situation, Task, Action, Result. Emphasise your learning strategy and what you delivered.
