They often underestimate the importance of interview preparation, assuming their knowledge and experience will be sufficient. Surprisingly, it's not their technical skills that hold them back. This article highlights some of the major reasons which gets neglected during interview preparation and offers insightful tips to assist experienced programmers in their interview preparation journey.
iOS Interview Prep — Concurrency
Concurrency refers to the ability to perform multiple tasks simultaneously. It’s useful for improving the performance and responsiveness of the app, as it allows different parts of the app to run independently without blocking each other. In interviews, concurrency is often a prominent topic, particularly for senior positions. Candidates should anticipate questions related to Grand Central Dispatch (GCD) and Operation Queues, as these are commonly discussed in relation to concurrency.

In the world of iOS development, many developers tend to default to using Arrays for collections in Swift. However, it is recommended to pause and consider if a Set would be a more suitable choice. Sets not only provide improved performance but also offer a range of powerful methods for comparing Sets. Interestingly, this topic is frequently addressed in iOS interviews, making it essential for developers to be familiar with the advantages of Sets over Arrays in Swift.
