First, they assigned a case study to test programming skills. For my case, it was a simple hotel room booking system which contained both frontend and backend parts. If you are familiar with one of the popular frontend frameworks, e.g., Vue, React, or Angular, and also its ecosystem, the test will not be too hard for you. You have 7 days to finish it.

One week after submitting the case study, they invited me to do the first phone screen interview with one of the recruiters. It was basically a getting-to-know-you session about your background and work experiences. No technical questions were asked during this interview.

One week after the first interview, they informed me to confirm a day in the next week for the second phone screen interview. The second interview was hosted by a hiring manager and a business partner. The questions were mostly about your motivations, work experiences, personality, and a few technical questions. Preparing beforehand why you applied to Trivago and what you did in your previous projects would be helpful to answer.

Then, one week after the second interview, they invited me to the third phone screen technical interview, which was held by a hiring manager, a project manager, and an engineer. The questions were basically about your case study, previous projects, understanding of some frontend technologies, and what you would do when facing difficulties.

At the end of the third interview, they said they would inform me of the result the following week. It actually took two weeks, and they said they had proceeded with another candidate.
