Western Union Software Engineer Interview Questions
& Process

It was a 3 stage interview process: a 15 minute phone screening, then a 1 hour technical interview with a Senior Engineer, and finally a 1 hour code challenge with a senior architect. It was pretty difficult to understand the interviewers because they were from out of the country. The whole process took less than 2 weeks and was conducted entirely over Zoom.

it 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.

Applied online. Had an initial recruiter screen where they asked some basic Java questions. Then I moved on to a second round technical phone interview with the hiring manager. They asked about my background and experience, what I did in past projects, and some technical stuff.
