Sample Wipro interview questions

From our curated bank of 11 Wipro-specific questions. The generator produces fresh AI-tailored questions each run.

• 1

  What is the Wipro NLTH (National Level Talent Hunt) and what does it test?

  Tip: NLTH tests English Communication, Analytical & Logical Reasoning, Quantitative Aptitude, and a Written Communication module. The combined Tech + HR interview follows for shortlisted candidates.

• 2

  What is the difference between abstract class and interface in Java? When do you use each?

  Tip: Abstract class: can have state, constructors, method implementations — use for "is-a" relationships with shared behaviour. Interface: contract only (Java 8+ allows default methods) — use for "can-do" capabilities. A class can implement multiple interfaces but extend only one abstract class.

• 3

  Write a program to check if a string is a palindrome.

  Tip: Two-pointer approach: compare characters at start and end indices moving inward, O(n) time O(1) space. Wipro also asks variants — palindrome ignoring spaces/punctuation, or finding the longest palindromic substring.

• 4

  Explain the MVC architecture pattern with an example.

  Tip: Model (data/business logic), View (UI presentation), Controller (handles user input, orchestrates Model + View). Use a simple web app example — user submits a form, Controller validates, Model saves to DB, View renders confirmation.

• 5

  What is a binary search tree? What are its time complexities for insert, search, and delete?

  Tip: BST property: left < root < right. Average case O(log n) for all operations on a balanced tree. Worst case O(n) for a skewed tree (all nodes inserted in sorted order). Know AVL/Red-Black trees as balanced BST variants.
