iOS interview: questions and tasks explained

A job as an iOS specialist is full of great opportunities. However, the requirements for this position can be overwhelming. With a little bit of luck and a little more work anyone can prepare for the iOS interview and surprise the recruiter with one’s knowledge and skills. We have a few tips on how to do that for both novice developers and experienced experts!

iOS interview questions: what to expect?

The very first conversation with recruiter, whether it is on the phone or in person, is always a huge challenge. As we all know, the first impressions are often the most important ones in the process. Above all, it is important not only to behave well, but also to answer the given iOS interview questions specifically. No overthinking or lying about one’s knowledge!

Junior and mid iOS engineers must, above all, show that they know the basics of their trade. The common iOS recruitment questions in the matter include the difference between two concepts. For example, this category may include classes and structures, static and class or frame and bounds. Moreover, candidate should also have some knowledge of protocols and memory security. If the prospective employee knows the project he plans to join, he should also be familiar with the tools and technologies it requires to land a dream job in IT.

Still, on each and every iOS interview one may encounter some questions he can’t answer.  Even in such a nerve-wracking situation you can buy some time. All you need to do that is to ask for a glass of water at the beginning of the conversation. Whenever you need a moment to think, take a sip from it and think about the right answer to the problematic iOS question.

Solving iOS recruitment tasks made easy

Problem solving is one of the main responsibilities of each and every developer. Therefore, questions on the interesting challenges one has encountered in his career are popular even in the biggest corporations. Even Apple uses this type of question – candidates applying there are often asked to choose the most demanding projects they have ever faced. But it is not the problem that really matters in this part of a process. Stress is the biggest opponent here, as it increases the difficulty of the iOS recruitment task.

However, stress can be significantly reduced when a candidate is properly prepared for the most popular iOS interview questions. Many of them repeat themselves across different software development companies. This category often includes algorithmic and data structure, with tasks such as sorting the tables or finding duplicated fragments. Those iOS tasks are especially valued among recruiters, as they test candidate’s analytical and abstract thinking.

iOS interview: more than just finding the answer

– Other problems you may encounter during an iOS interview are refactoring tasks involving quality maintenance in the given project. Problem solving itself can also be used as a test for a candidate. This type of exercise can be very diverse. That is why one should get familiar with the technologies used in the project before coming to an iOS interview. Those tasks usually include some features used in the company during an everyday work. – says Rafał Prążyński, iOS Software Engineer in Ailleron.

What is more, iOS recruitment tasks given to candidates during the interview does not have to have only one solution. In fact, they do not have to have a solution at all. Sometimes companies do not want their prospective employees to find the right answer. They just want to test his thinking and logic in general. Thinking out loud can be extremely valuable in such a case. It can both show candidate’s thinking and help him find one of the acceptable solutions. Thus, one should not give up when seeing a difficult iOS interview question – sometimes we just need to show our determination and knowledge to impress the recruiters.

Unsuccessful iOS interview turned into success

Not every iOS interview goes as smoothly as we may expect. Searching for a job is full of difficult questions and problems that we cannot solve right away. That does not mean that such a task should quickly be forgotten; it’s actually the opposite. Such a failed task has a potential to become a source of knowledge that can be useful in the future.

It is worth to remember that a candidate can ask recruiters for the right answer to difficult questions. He can even do so during the interview itself. If a prospective employee is rejected, he can contact the company to ask for a feedback. That will allow him to get more details regarding the reason for such a decision. Based on that set on information we can prepare better for the upcoming interviews. More importantly, this also helps us broaden our horizons. They can be used more often than just during recruitment process.
