My single tip for clearing the first two phases of the interview

When it comes to preparing for an iOS interview, having a strong portfolio of client-side development projects is crucial. However, for many candidates, a portfolio alone may not be enough to stand out from the competition. This is where spending time working on your own app and putting it on the App Store can make all the difference.

Creating your own app allows you to demonstrate your skills and knowledge of iOS development in a way that a portfolio of past projects may not. It shows that you have a passion for the field, and that you are willing to take initiative and work independently. Even more importantly, it allows you to showcase your ability to deliver a functional and high-quality product.

But what kind of app should you create? The answer is that it doesn’t have to be overly complex. In fact, a simple and functional app can be just as effective as a more complex one. The key is to demonstrate your understanding of the platform and your ability to create a functional product.

When creating your app, it’s important to keep in mind that the main goal is to impress your interviewer. This means that your app should be easy to run, build, and profile, and it should be well-tested and properly documented. It should also follow a clear design pattern, such as MVC or MVVM, and should avoid the use of third-party libraries as much as possible.

In addition to the technical aspects of your app, it’s also important to focus on the user experience. A well-designed and visually appealing app can make a big impression on an interviewer, and can help set you apart from the competition.

Spending time working on your own app and putting it on the App Store can be a great way to demonstrate your skills and knowledge of iOS development. A well-made app can be the key to impressing your interviewer and standing out from the competition. So, take the time to create a functional and high-quality product that showcases your understanding of the platform and your ability to deliver a great user experience.

Take-home challenges

Take-home challenges can be intimidating, especially if you’re not sure what to expect. I’ll discuss what take-home challenges are, why they’re used, and how to prepare for them.

A take-home challenge is a project or task that a candidate is given to complete on their own time, typically outside of the traditional interview setting. These challenges can range from building a simple app to solving a complex problem or debugging an existing codebase. The purpose of a take-home challenge is to give the candidate an opportunity to showcase their skills, problem-solving abilities, and attention to detail. It also allows the employer to get a sense of how the candidate works, how they approach a problem, and what their code looks like.

Take-home challenges can be a great way for candidates to stand out from the competition, as they provide an opportunity to demonstrate your abilities in a real-world setting. However, it’s important to remember that take-home challenges can also be time-consuming and stressful.

So, how do you prepare for a take-home challenge?

The first step is to understand the requirements and the scope of the project. Make sure you have a clear understanding of what is expected and what the deliverables should look like. If you have any questions or concerns, don’t hesitate to ask the employer for clarification.

Next, it’s important to plan your time and set realistic goals. Take-home challenges often come with a deadline, so it’s important to manage your time effectively and prioritize tasks. Break the project down into smaller tasks and set deadlines for each one. You should also make sure you have the right tools and resources. This includes any necessary software, documentation, or sample code. Familiarize yourself with any frameworks or libraries that may be used in the project. It’s important to practice good coding practices. This includes writing clean, readable, and well-documented code, as well as testing your code thoroughly. Make sure to pay attention to detail and double-check your work before submitting. Take-home challenges can be a great way for candidates to stand out from the competition and showcase their skills and abilities. By understanding the requirements, planning your time, having the right tools and resources, and practicing good coding practices, you can feel confident and well-prepared for your take-home challenge.

Some common examples of take-home challenges include tasks such as fetching JSON and displaying the results, adding a new feature to an existing codebase, and finding and fixing bugs in a project. When given an open-ended, project-based task, it is important to ask clarifying questions to ensure you understand the company’s expectations. They may have specific coding styles, architectural patterns, or frameworks they would like you to use. Make sure you understand the requirements before starting the task.

Onsite/Online interview with Team Members

The onsite or online interview with iOS team members is an important step in the iOS interview process and it is the most challenging part of the whole process. This is your chance to showcase your technical skills and knowledge, and to demonstrate how you will fit in with the team. In order to ace this part of the interview, it’s important to be prepared and to understand what the team is looking for.

First and foremost, it’s important to be familiar with the technologies and tools that the team is currently using. This includes programming languages, frameworks, and tools that are specific to iOS development. Make sure you have a good understanding of how these technologies work and how they are used in real-world applications.

It’s also important to be prepared to talk about your past experiences, and to be able to give specific examples of how you have used your skills and knowledge in a professional setting. Be ready to explain how you have solved problems, and to give examples of the projects you have worked on and the technologies you have used.

In addition to your technical skills, the team will also be interested in your problem-solving abilities. Be prepared to answer questions about how you approach problem-solving and how you think about different types of problems. This could include questions about your debugging process, your ability to troubleshoot issues, or your ability to come up with new solutions to problems.

Another important aspect of the interview is the ability to work well with others. The team will be looking for someone who can collaborate effectively and who can work well in a team environment. Be prepared to talk about your experience working on a team, and to give specific examples of how you have contributed to a team’s success.

Finally, be prepared for the interviewer to ask some general questions about your interest in the company and your motivation for wanting to join the team. Show your enthusiasm and your interest in the company’s mission and values. Be ready to ask questions about the company and the team, as this is a good opportunity to show your interest and to learn more about the company culture.

With the right preparation, you can ace this interview and take one step closer to landing your dream job.

Before you begin the negotiation process, it’s important to do your research. Know the market value for iOS developers in your area and have a clear idea of what you are looking for in terms of salary, benefits, and other perks. This will give you a strong starting point for the negotiation process.

When discussing the salary, it’s important to keep in mind that it’s not just about the base salary. You should also consider other compensation such as bonuses, stock options, and benefits.
