LTI Interview Questions (QA Automation)

One of my friends recently gave an interview at LTI.

Here are the 19 questions they faced - useful for anyone preparing for QA/Automation roles:

Technical Questions

1. Can you briefly explain your work experience in automation testing?

2. How many years of experience do you have in automation, and what frameworks have you worked on?

3. If you were to rate yourself out of 5 in automation tools (like Selenium, Cucumber), what rating would you give?

4. What is your knowledge of TestNG annotations and parallel execution?

5. Do you have any experience with JMeter?

6. What is your experience with Postman for API testing?

7. Do you have any exposure to REST Assured?

8. Why did you move from Selenium to Playwright? What advantages does Playwright provide?

9. Can you explain how you apply OOPS concepts in your automation framework?

10. Limitation of selenium?

11. What are Lambda expressions in Java? Why are they used?

12. Which version of Java are you using?

Scenario-Based Questions

14. A defect is reported in production. How do you handle it?

15. During regression testing, you find 200 test cases failing.

What's your approach?

16. You are asked to automate a CAPTCHA field. What will you do?

17. Your login test is failing intermittently. How do you debug?

Top Coding Interview Questions 💻

📍 1. Two Sum Problem
Find two numbers in an array that add up to a target value.
Approach: Use a hash map to store complements for O(n) time.

📍 2. Reverse a Linked List
Reverse a singly linked list iteratively or recursively.

📍 3. Binary Tree Traversals
Implement Inorder, Preorder, and Postorder traversals (recursion or stack).

📍 4. Detect Cycle in a Linked List
Use Floyd’s Tortoise and Hare algorithm to detect if a loop exists.

📍 5. Merge Intervals
Given intervals, merge all overlapping intervals.

📍 6. Valid Parentheses
Use a stack to check for matching pairs of parentheses/brackets.

📍 7. Maximum Subarray Sum (Kadane’s Algorithm)
Find the contiguous subarray with the largest sum.

📍 8. Search in a Rotated Sorted Array
Modified binary search to find an element in a rotated sorted array.

📍 9. Implement Queue using Stacks
Use two stacks to simulate a queue’s FIFO behavior.

📍 🔟 Least Recently Used (LRU) Cache Implementation
