214 senior mobile engineer interview questions shared by candidates

The process was pretty complex and it was simplified a bit since then, and it was pretty impressing. They don't do any silly gotcha coding questions. They do test basic CS fundamentals pretty heavily, but they are smart about it. Mobile platform questions. Simple coding question in Java, Objective-C and C++, questions about platform API (basics to check if you really code in it), and multithreading concepts. Take home assignment - optimization problem (I believe they don't do it any more) with elements of OOD. On-site coding round (leetcode style puzzles, basic CS concepts, data structures, threading, memory management, code review). On-site design round. Designing complete mobile app, frontend and backend (architecture, no visuals). Discussing various constraints, changing requirements as you go, to check if your design is adaptable. On-site company culture fit round with manager. HR round with compensation expectations. On-site team culture fit round with direct team lead.

What are your thoughts on single-activity architecture? If a junior developer comes to you and asks why view models are needed, what would you tell them? What's your experience with coroutines? What's the role of an interceptor with Retrofit? What's your unit test strategy? Have you ever worked with instrumentation testing? What language is Gradle written in? What alternatives are there to LiveData?
