What to look for in an Android developer

Android is the most prevalent mobile operating system in the world, running on countless smartphones, tablets, and other devices. So finding a good Android developer should be easy, but such high demand actually makes the hunt pretty tough, as there are always competitors waiting to steal the best developers away. That means you will have to screen candidates quickly and efficiently to find the right ones and you will need to know what to look out for.

A good Android developer will need to be up to date with the latest advances in the operating system. They will also have to be well versed with Java programming: workshops, certificates, and knowledge of patterns.

You will want to know how many publications and production issues your candidate has worked on, personally rather than as part of a team. An experienced developer will be able to provide various projects they have worked on and give examples of problems they have solved.  Your Android developer should be able to demonstrate a basic knowledge of the family of libraries that each application uses, including CardView, RecyclerView, Floating Action Button, Toolbar, and Navigation Drawer.

Build your own custom Android interview questions and tests

Like what you see, but want to adapt the tests to your own preferences? No problem. The DevSkiller online task wizard comes ready-made with features allowing you to customize every Android test you send out. How long each test lasts, the difficulty level, and even the time allocated for each question, can all be set based on your needs. All testing is carried out remotely meaning tests can be taken at any time and results are provided automatically.

Need assurance that our Android interview questions and tests work?

If you think DevSkiller Android interview questions and tests are what your business needs, but you’re not 100% committed, have a look at what one of our clients has to say:

StepStone is a group of leading job boards that operate all over the world. All of the company’s software is designed in-house in their IT department, StepStone Services, where 300 developers work on IT products from across the globe.

The problem StepStone Services had was their screening process for new developers was time-consuming and required too much manual labor. The process involved practical tasks sent by email, followed by pen and paper tasks set during the technical interview.

In 2017 StepStone enlisted the help of DevSkiller to assess their candidates’ knowledge in order to get an understanding of their coding skills, while also saving on time and labor.

Victoria Chyczewska- Talent Acquisition Specialist at StepStone Services

“Phone screening followed by a DevSkiller assessment allows us to decrease the number of onsite interviews by up to 40%. We increased company fit thanks to custom tests and, as a consequence, we now only spend onsite interview time on candidates who really show a lot of promise. Our Time to Hire is now shorter because our technical screening process is automated.

Frequently asked questions

How are Android interview questions and tests evaluated?

The DevSkiller platform is automated, meaning it gets to work the moment the candidate finishes the Android test. The results are specially designed to be simple and easy to follow for even those non-technically minded and candidates are assessed on whether the solutions they have provided would be likely to work. They are also evaluated on the quality of their coding and any mistakes made and how it works in edge cases. Anti-plagiarism tools ensure the validity of the results.

How do candidates undertake an Android test?

Devskiller’s Android online tests can be accessed remotely from anywhere in the world, meaning all the recruiter has to do is send out test invites. Invites can even be made available for a limited amount of time and candidates can choose to start the test whenever they want to.

When taking tests candidates can opt to use DevSkiller’s state of the art in-browser IDE or to complete the project on their favorite IDE and clone the project to GIT. If they need to, candidates can run unit tests to make sure their solutions work. The time- limit for each test can be set and once the time expires the test is automatically evaluated and the recruiter receives a report on the candidate’s

What do you do about plagiarism?

If you’re thinking a candidate might be able to cheat to gain the upper hand, then think again.

DevSkiller has tools in place to ensure you only receive accurate results. Screen checks ensure candidates aren’t looking at a different screen when undertaking a test and plagiarism detectors automatically scan the entered code and cross-reference this with every answer in our test database. If there is a match, it is because the candidate has cheated.

How long does it take to complete an Android test?

The duration of each Android test depends on your needs. Tests come with default duration settings, which can be easily altered if required. Even individual questions within a test can be defined.
