I just made it past the initial screening for a technical interview with a well-known food delivery app, but I've never worked with mobile apps before. I have about five years of experience in DevOps and am familiar with tools like Docker, Kubernetes, Terraform, and others. I'm looking for tips on what I should focus on to prepare for this interview, especially since mobile apps seem to be a different ball game.

Even though I haven't worked with mobile apps either, consider these points: What do the build pipelines look like for Android vs. iOS? How is software delivery different for mobile apps? And what about observability in those environments?
It might be useful to familiarize yourself with how mobile teams manage infrastructure scaling and handle edge cases. Plus, understanding the complexities with push notifications and the app store release cycles can really help.
I'm not in the food delivery sector, but I'd suggest brushing up on protocols that deal with real-time app sensitivities. Start with NTP/PTP and then look into how to gather and process performance metrics in real-time. The tech stack might vary, but the concepts will be similar across the board.
For Android, it usually involves a typical Gradle build, but the automated testing can get tricky. That's more of an issue for developers and QA. For iOS, it can be quite challenging—XCode can be a nightmare, so hopefully they're using a robust CI/CD service to handle that automatically.
