Sample Capgemini interview questions

From our curated bank of 10 Capgemini-specific questions. The generator produces fresh AI-tailored questions each run.

• 1

  What is the Capgemini SMART (Sophisticated Multidimensional Aptitude and Reasoning Test)?

  Tip: SMART is a game-based assessment measuring attention, memory, problem-solving speed, and spatial reasoning — not traditional MCQ aptitude. You play puzzle-like mini-games. There is no specific preparation material; focus on accuracy over speed.

• 2

  What is the difference between HashMap and HashTable in Java?

  Tip: HashMap: not thread-safe, allows one null key + multiple null values, generally faster. HashTable: thread-safe (synchronized), does not allow null keys/values, legacy class. For thread-safety in modern Java, prefer ConcurrentHashMap over HashTable.

• 3

  Write a program to implement a stack using two queues.

  Tip: Push-costly approach: on push, enqueue to queue1, then transfer all of queue1 to queue2, swap references. Pop is O(1). Pop-costly approach reverses this. Capgemini likes data-structure transformation problems — know both approaches.

• 4

  Explain the concept of design patterns. Give an example of a Creational and a Structural pattern.

  Tip: Creational: Singleton (one instance, e.g. DB connection pool), Factory, Builder. Structural: Adapter (wraps incompatible interface), Decorator, Facade. Behavioural: Observer (event listeners), Strategy. Capgemini enterprise projects use patterns extensively.

• 5

  What is Big O notation and why does it matter in practice?

  Tip: Big O: upper bound on growth rate of time/space as input size n increases. Matters because O(n²) becomes unusable at n=10,000 while O(n log n) handles n=10M. Common hierarchy: O(1) < O(log n) < O(n) < O(n log n) < O(n²) < O(2^n).
