Follows star methodology and prepare for several behavioral questions: --Can you describe a time when you came up with an innovative solution to a problem? How did you implement it? -Describe a situation where you had to work under pressure or handle multiple competing priorities. How did you managed it?

Q1. Write a code to print duplicate words in a string and write unit test cases for the code written.
Round 2: - What is the difference between - String, StringBuilder, StringBuffer? - What is the difference between - Abstract Class vs Inheritance? - When will you go for Abstract Class and When will you go for Interfaces? - Given arr1 = {1, 12, 15, extra space1, extra space 2, ... ,extra space N}, arr2 = {2, 4, 35}. Merge these two sorted arrays in arr1 without the help of a third array. Makes sure that arr1 is also sorted. Give an O(1) solution. - Balance the given parentheses. - Given an array - Find the sum pairs which satisfies the condition a+b = c+d in the array
Problem Statement: There's a queue which has N producers at one end and N consumers at the other end. The Producers get their input from an SDK. The queue actions can be controlled by APIs. Now When there are 1000+ orders placed in a minute in Myntra portal, come up with a solution in the framework on how you will validate the packets sent and received are the same in the Queue? Note: Here there are N producers and N consumers. Any consumer can receive a packet from any producer. There can also be scenarios that Queue is blocked and not flushed at for a very long time. Due to high traffic, the queue may not drain all the packets at the regular period of interval. Keep all the negative scenarios in mind while designing this framework.
Lowest common ancestor of two given nodes within a binary tree.
NDA Helpful Notes: Go though data structures, algorithms and collections. The technical interviews will mainly focus on testing strategies and coding skills. You might be asked to write up test cases for multiple services. Be sure to cover all negative cases, edge cases, happy path scenarios and dependencies. It will help if you practice enumerating test cases for websites, algorithms and functions. For coding questions, I think they are looking to see if you come up with the strategy. They might ask you to implement the solution in a different way. If you can give them a fair idea about your analysis on how to address the solution, I think that should be sufficient. Be prepared for database queries. Joins and normalization in specific. Apart from that, you can expect process related questions related to bug tracking, metrics, CI/CD, release management etc. Automation and REST services questions were also part of the mix (If you work with technologies like Selenium, they will ask you specific questions related to it).
Normal question on testing and Selenium.
Not specific..they will ask as per the flow go and how comfortable you are in a topic.
