Ian Hwang

Software Engineer

Placed at:

I attended IK and I've got a lot of knowledge that helped me get into Microsoft. Their Curriculum (algorithms and data structures) is organized very well and explanations are so helpful. And mock interviews and the feedback helped me a lot. It was worth it!

Neetika Srivastava

Software Engineer

Placed at:

I really like how the program is structured and how it caters to different domains. It is really helpful. The patterns that they teach you at Interview Kickstart are really useful because you can apply those patterns to any new problem. Knowing those patterns, you can solve basically any question because you can relate it to problems you have already solved, which gives you confidence.

Chun Wu

Senior Software Engineer

Placed at:

I joined iK after stumbling across it while reviewing some other interview prep materials after doing poorly in an interview at Linkedin. I knew that doing well in these interviews would require dedication and investment of my time - but with so many resources online I didn't have structure. This is what the IK platform provided me.

Shrey Shrivastava

Software development Engineer ll

Placed at:

The Interview Kickstart course is very structured and informative. They teach you about DS and algo fundamentals very thoroughly and also prepare you for the software engineering interview. I really like the live classes by FAANG engineers, and the homework and tests definitely help you toprepare for a real interview. If you have been looking for a bootcamp that prepares you for software engineering interviews, I would say this is definitely the right place to do it.

Sridhar Gandham

Senior Software Engineer

Placed at:

My experience at IK was extremely positive. I was preparing for FAANG companies using the standard techniques that you find on the internet. When I started preparing, there was no structure to the madness. For example, a simple quicksort can be implemented in multiple ways. So solving a medium problem would take me about 30 minutes. The biggest benefit that I got from IK was a clear, structured way of solving problems. After IK, I could solve medium problems in 10 minutes!

Android Engineering Interview Process Outline

A typical Android Engineering interview process at FAANG+ and other Tier-1 companies looks like this:

Initial technical screening: This usually involves a DSA-based coding round and a discussion of your past projects and Android fundamentals.

4-6 on-site rounds:

General coding rounds – Leetcode-styled questions [language agnostic; better if one can code in Kotlin or Java]; your coding skills are evaluated.
Android-specific interviews – Mix of Android flavored DSA questions; Android Domain knowledge testing through trivia questions.
System design – Client-side system design – Whiteboarding solution; general structured problem solving is evaluated with questions such as, “Design Instagram.”

At other Tier-1 companies like Uber, Pinterest, Airbnb, Doordash, etc., following rounds are also a part of the interview process.

Take-home assignments
Live coding – Coding an Android application from scratch within time limits
Code slicing – Understanding an existing piece of code and building some features on top of it
Code debugging – Identifying and fixing bugs in the project

Behavioral round: Open-ended questions asked by hiring managers to gauge whether you’re a cultural fit for the company

What to Expect at Android Engineer Interviews at FAANG+ Companies

Initial technical screening

This usually involves a coding round and a discussion of your past projects and Android fundamentals. The coding questions are typically at an Easy/Medium level on Leetcode.

Follow-up technical phone screen

Conducted by Android Engineers through a phone screen, this is an option round of interviews and is conducted for only some of the candidates.

On-site (around 4-6 rounds)

On-site rounds vary a lot from company to company. Some companies have all the following components in all of their rounds. Some companies prefer to have 2-3 explicit algorithmic coding rounds first then, followed by a couple of rounds on Android domain concepts and Android system design.

Algorithmic questions: Depending on the total years of experience, you go through 2 to 3 coding (DSA-based) rounds. Usually, the difficulty level of these questions is LC easy/medium, but occasionally LC hard questions are also thrown into the mix.
Android Fundamentals Round: You are grilled on their knowledge of Android development- Design patterns, views, and User Interaction. You might also be asked to develop an Android app.
Bug fixing: Fix bugs in a given app codebase within a given time interval.
Slicing of code: Explain the working of a given piece of code.
Android Systems Design Rounds (Generally for experienced candidates): The number of design rounds typically increases with your work experience and applied level. You are also expected to explain low-level design implementation as well for some parts of the HLD. You are also tested on high-level design architectures for real-life products.

Behavioral round

This is conducted by the hiring manager. Expect questions related to your job experience, discussions on past projects, and open-ended questions to gauge if you’re a “good fit.”

You can apply for the open job roles through online channels or through recruiters. Once your profile is shortlisted, you’ll go through these rounds of interviews. The entire interview process takes around 4 to 8 weeks.

Android Engineering Interview Questions

As Android is the most popular operating system in the world, the demand for qualified professionals is always increasing. To clear the interview questions at the top tech companies, you’ll need to know which Android Engineering interview questions to prepare.

To help you get started, we’ve divided them into the following categories:

Android Engineering Interview Questions on Coding

How do you convert a String into int like the atoi()?

What’s the process of reversing a linked list in place?

How would you remove duplicates if given an array in Java?

What’s the process of determining whether a given number is a palindrome?

How would you implement the Sieve of Eratosthenes Algorithms for Prime Number?

Domain-Specific Android Engineering Interview Questions

Evaluate two different ways to design an app that horizontally scrolls, like when you select an email in Gmail:

Come up with how to implement a horizontal scroll where:

- The user can scroll multiple items at a time
- The user can’t, and each item snaps stop

Describe how you would:

- Figure out which one is in the middle
- Update the elements on the top/bottom of the screen to match the data that’s in the middle

How would you implement the feature in an existing application?

Scroll position persistence

- Given: A user has navigated to a location within the minute data list
- When: the user closes the app and relaunches it
- Then: the minute data list scroll position is the same

Navigation persistence

- Given: A user has navigated to a specific minute’s detail screen
- When: the user closes the app and relaunches it
- Then: the minute data detail screen is the same, and a back press takes the user back to the list screen.

The app has a login and logout button, and if the user tries to log in (simply by pressing the login button), all buttons should not work. Please check out how to solve this ANR so that the static simulation works (i.e., the top right button).

Design a messenger application with the following requirements:

Design a messenger app where users can send messages to each other
We do not need to implement group chat
Provide support for offline (view contacts, send messages, not receiving messages, though, obviously)
Users can share images in the chat

Architect and write the fragment + adapter code to implement infinite scroll for an application.

Why do you need an AndroidManifest.xml file?

Differentiate between Implicit and Explicit Intent.

What is meant by ANR in Android, and how can it be avoided?

What troubleshooting techniques can you use if an application crashes frequently?

In Android Development, what is the role of Dalvik?

How would you implement a GDPR program for Google Services?

What’s the importance of the .dex file?

Define Job Scheduler.

What are the drawbacks of Android?

Explain the four essential activity states.
