they were two people started with greetings! and following my introduction 😊 I was not much prepared specific for the drive but pretty much confident for whatever I was telling. Next they asking me for pen-paper coding question. Question was just to get the second largest number in the array. So, first I started with sorting method. Then the began asking asking how do you sort that ? — I explained Merge sort algorithm to them. Again then I told this is not much good approach, better we can just use 2 variables and keep storing highest and second highest number of the array. Like this, they were impressed by optimized solution.

The interview process at Western Union typically involves multiple stages designed to assess both technical competencies and cultural fit. While the exact process may vary depending on the position and location, candidates can generally expect the following rounds: **1. Online Assessment:** The initial stage often includes an online test comprising multiple-choice questions (MCQs) and coding challenges. For instance, candidates have reported encountering a 90-minute test with 58 MCQs covering aptitude and computer science fundamentals, along with a coding question focused on algorithms like dynamic programming. citeturn0search0 **2. Technical Interviews:** Candidates who pass the online assessment proceed to one or more technical interviews. These sessions delve into various topics, including: - **Data Structures and Algorithms:** Problems related to sorting algorithms (e.g., bubble sort), string manipulation (e.g., checking for palindromes), and pattern-based coding challenges. citeturn0search2 - **Object-Oriented Programming (OOP):** Discussions on concepts like polymorphism, method overloading vs. overriding, and the four pillars of OOP. citeturn0search1 - **Database Management Systems (DBMS):** Writing SQL queries, understanding foreign keys, and differentiating between Data Definition Language (DDL) and Data Manipulation Language (DML) commands. citeturn0search0 - **Computer Networks:** Questions on the OSI model and related networking concepts. citeturn0search0 - **Programming Languages:** Specific questions about languages pertinent to the role, such as Java, including topics like multiple inheritance and Java memory models. citeturn0search2 - **Project Experience:** In-depth discussions about the candidate's past projects, focusing on technical challenges faced and solutions implemented. citeturn0search1 **3. HR Interview:** The final stage typically involves an HR interview to evaluate cultural fit and assess behavioral attributes. Common questions include: - "Tell me about yourself." - "Describe your family background." - "Why do you want to join Western Union?" - "Where do you see yourself in the next 3 to 5 years?" - Situational questions about teamwork and handling project group dynamics. citeturn0search0

3 stage interview: 15 minute phone screening, 1 hour technical interview with Senior Engineer, 1 hour code challenge with senior architect. Very difficult to understand as interviewers are from out of the country. Process took less than 2 weeks and was all through Zoom.
