Viagogo Software Engineer Interview Questions
& Process

It was about an hour long, and I was asked several algorithm questions, including sorting and linked lists. I managed to answer them all, though some required a bit more time due to twists. The interviewer seemed busy and impatient, never turned on their camera, and didn't answer my additional questions. It didn't feel very professional and was a bit hostile. No offer was made.

The whole process took about two weeks. It started with a casual chat with someone from HR. After that, there was a technical interview over the phone with two of the company's engineers. During the technical part, the interviewer basically asked how I was doing and then we went straight into a coding challenge. While I was coding, the interviewer kept muting the call to talk to a colleague, which felt both rude and intimidating. About halfway through the coding section, they stopped me, said "I can see what you are trying to do but still it will not be so efficient," and then asked if I had any questions before ending the call. It was the only interview that made me feel so intimidated and disrespected.

Viagogo has a multi-stage interview process. I went through 3 stages, but I think there are 4 in total. First, a phone interview with basic personality questions, asking why I chose my course, my passion for it, and my passion for working at Viagogo. Then, a coding challenge that presented a simplified real-life problem, like calculating the shortest path between two points on a 100x100 grid. After that, a phone coding assessment with the lead engineer where I had to demonstrate practical skills. This involved two challenges: optimizing the complexity of finding an integer in an array, and an OOP test. The final stage is an in-person interview, which I didn't reach.
