First-hand accounts from people who interviewed at trivago.
Front End Developer
I went through 4 interviews for the Front End Developer role. Two were remote and involved a single technical interviewer. The other two were in person at their Dusseldorf headquarters. The first in-person interview was with two senior technical people, and the final one was with the CTO. Although I didn't get the job, they did reimburse my travel costs. They didn't really make me feel welcome though, and didn't seem very concerned about me.
- Can you explain the difference between Progressive Enhancement and Graceful Degradation?
- What are considered best practices when using Jquery and vanilla JS?
- What are the best practices for CSS selectors?
Frontend Engineer
I applied directly through the website link for the Dusseldorf position. The interview process involved two main stages. First, there was a case study that was given a week to complete, which was relatively easy. The second interview consisted of a discussion about the case study and a simple JavaScript coding exercise on an IDE.
- Can you tell me about JavaScript fundamentals?
- What are some basic JavaScript functionalities you're familiar with?
- Could you implement some simple JavaScript code?
Senior Frontend Developer
I applied online and then I was given a task to work with PHP + JS for the role. I had to create a docker container with an API server and a SPA. It took me more than 7 days to complete. I felt it was unprofessional to assign such a big technical task without even talking to HR first.
- Build a docker container that includes a PHP API server and a SPA using React or Vue.
