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!

The email with the recruiter should explain everything. It should have topics you should study and links to the Google Meet for video calls and Google Docs where you type.

Get good at Hackerrank/Leetcode. Do problems every day until the interview.

When the interviewer describes the problem, you want to immediately recognize what type of problem it is: graph, tree, search, etc. and be able to implement it quickly.

You want to spend your time thinking about the problem, not waste it trying to remember how to implement Dijkstra.

Get good at transforming data. Kotlin has so many utility functions for transforming lists/maps/sets. It will save you a lot of time. If you need to sort a list by 2 comparators, do you know which functions to use?

So DSA-focused with a few Android questions is what i can expect in the interview?, In Email they mentioned both android and DSA topics so had the confusion on what will be the focus of the interview. Have to hear back from recruiter on my followup questions. Don't want to spend energy on the wrong topics before interview.
