10 Essential Mobile App Interview Questions and Answers

Ipa file is an https://remotemode.net/ application archive file that stores an iOS app. Each ipa file includes a binary and can only be installed on an iOS device. A web application runs inside a mobile web browser, such as Chrome, Firefox, Opera, Safari using a mobile network or WIFI. For instance, some of the web applications are m.facebook.com, m.gmail.com, etc. Autorelease pools are a convenience that allows you to defer sending -release until “later”. That “later” can happen in several places, but the most common in Cocoa GUI apps is at the end of the current run loop cycle.

And once the developer meets the requirements, it’s time to set up the interview. With strong attention to detail, he has created many great apps and has delivered many projects for millions of users, both startups and big companies. A positive attitude allows him to create on his own and in teams. There is more to interviewing than tricky technical questions, so these are intended merely as a guide. Not every “A” candidate worth hiring will be able to answer them all, nor does answering them all guarantee an “A” candidate. At the end of the day, hiring remains an art, a science — and a lot of work.

What are the main features and advantages or disadvantages of Swift?

The interviewer is asking about a process you would use that involves elements of technology. Keep in mind that your answer should be brief and to the point when answering these types of questions. You should also anticipate follow-up questions from the interviewer indicating that they have a specific interest in this topic and want to explore it in more detail. This is an example of a general question the interviewer will ask to learn more about your background. Interviewers will ask a variety of questions throughout the interview. These will include general, technical, operational, situational, and behavioral questions. Recognizing the type of question you are being asked will help you determine how to best answer it.

  • The tests drive implementation and design of your production code, helping you write only the code necessary to pass the tests implementation, no more, no less.
  • If we hire you we will won’t give you more then 20k to your annual salary.
  • Where applicable, questions have further reading section where you’d find links and references to more material related to them.
  • Give me an example of a time you had to take a creative and unusual approach to solve a coding problem.
  • However, when you ask the right interview questions, the chances of securing a good hire increases.

Permissions can be granted or denied not only when the app is run but also from the user’s settings, so the app has to always check for it. To receive information from a server without polling via a series of requests, a mobile app might use push notifications. This is a better solution than constantly requesting new data, because it will not drain the battery and will use less network data. Localization (“l10n”), on the other hand, is the process of preparing the content of the app to be available in different languages. This includes translating most of the app’s resources, like texts, images, and sounds. Resources for different languages are usually kept in different files or directories, and the OS chooses the right one based on user settings.

Mobile App Developer Interview Questions and Answers

Many mobile developers make a mistake of calling any test object a mock, but there is a specific distinct nomenclature for test objects that indicates the purpose for each one. As a senior developer you’re not merely writing tests, you also should know how to maintain them as well as your application codebase. Singleton is a common design pattern used in many OOP languages, and Cocoa considers it one of the “Cocoa Core Competencies”. This question comes up on interviews to either gauge your experience with singletons, or find out if you have a background in something other than just iOS.
