Android Interview Preparation Guide

 July 8  | 0 Comments

Android is known as the world’s most popular operating system for mobile devices and tablets. It is an open source operating system which has been created by Google and is available to all kinds of developers with various expertise levels, ranging from rookie to professional.

Android is a platform that supports various applications, available through Android Play Store. The Android framework is licensed under the Apache License, with Android application developers holding the right to distribute their applications under their customized license.

The mobile device market is rising at a rapid speed. This growth is nurturing the demand for mobile application developers, creating a host of employment opportunities. Organizations are ready to provide a huge pay package to skilled professionals in this sector. According to Indeed, the average salary for Android is 102,000 USD, which is 77% higher than the average salaries of other job postings.

Based on the demand in the market, finding out an impressive portfolio for the position of Android developer has become a challenge. Android developer roles have become more specialized. Earlier we used to do the design and development of the client’s projects to show case in our profile, but modern day portfolio has changed. It now consists of:

• Applications deployed on Play Store
• GitHub profile with your own set of projects or Open Source contributions
• Your contribution towards Stack Overflow
• LinkedIn Profile Link etc.

The following will be required in order to apply for the Android job:


A cover letter typically explains the reasons for your interest in the specific organization and identify your most relevant skills or experiences. Only few companies ask for a cover letter these days. If you are required to supply a cover letter, make sure to address the given questions and write in a professional yet friendly manner.

Double-check your spelling and proofread the email to make sure it reads well. Ask someone to triple-check it.


First impression is the best impression so make sure your resume conveys your skills, value, experience correctly. It is always better to provide online version of profiles like LinkedIn, Stack Overflow. Also ensure that your resume is up to date with valid information.

If you are applying for top most companies then it’s always preferred to include your projects on Play Store or GitHub. Always be active in Stack Overflow, Quora, GitHub.

In addition to above points make sure Twitter feed, Facebook page, LinkedIn profile and so on are clean and represent your professionalism. Once you submit the resume to any of the company they will search online for you and thus these should be neat.
