In this video, we dive into a crucial aspect of technical interviews: the Mobile System Design Interview. This type of interview is highly important for landing a job at FAANG companies.

I’m Alexey Glukharev, a Senior Android Engineer at Lyft with extensive experience interviewing with multiple FAANG companies and conducting interviews myself. Today, we will design a chat application from the ground up, exploring key components and considerations for building a scalable and reliable system.

Join me as we discuss why system design interviews are a critical part of the hiring process, the skills they assess, and how you can prepare to excel in them. Don’t miss out on this opportunity to enhance your understanding and improve your interview readiness.

Additionally, I’ve prepared a list of great links about system design, specifically tailored for the mobile domain area:

Remarks:

The message service should connect to the controller to handle user commands (e.g., to send messages). It will observe the updated results from the database using a repository.
