Google L4/L5 Android Interview – What does the "Android Domain Knowledge, Programming, Data Structures & Algorithms" round actually involve?

Hi everyone,

I have an upcoming Google Android interview, and the interview schedule mentions the following:

  • One Android Domain Knowledge, Programming, Data Structures & Algorithms interview (45 minutes)
  • One non-technical behavioral interview (45 minutes)

I'm trying to understand what the first round is actually like.

A few questions for anyone who has gone through it recently:

  1. Is the interview primarily DSA-focused with a few Android questions, or is it mostly Android-specific (architecture, lifecycle, threading, Compose, performance, etc.)?
  2. If it's Android-heavy, what kinds of problems are typically asked?
  3. Are we expected to implement an entire Android feature (e.g., ViewModel, Repository, Compose UI, networking, etc.) in a plain text editor, or is it more like writing individual classes/functions or designing part of a system?
  4. Is the coding done in a Google Docs-style editor, a shared editor, or something with syntax highlighting?
  5. How much emphasis is placed on Android APIs versus clean coding, object-oriented design, and problem-solving?
  6. For those who interviewed recently (2025–2026), what topics would you recommend prioritizing?

I'd really appreciate hearing about recent interview experiences or any advice on what to expect.

Thanks!
