Technical questions and answers that will help you get a job, get promoted and become a better mobile developer.
Don't believe in all these courses from Hindus about building another master advanced React-Native application for selling shoes or a To-Do list in JavaScript. I will show you what real React-Native programming is.
Yearly net earnings of React-Native developers:
Junior: $45 000 - $82 000
Mid: $82 000 - $110 000
Senior: $110 000- $185 000
You don't have to immediately advance from junior to mid level. All you need to do is increase your competences a bit, and this may translate into additional earnings of $30,000-$40,000. This is the first course in a series that I plan. Its goal is to show you what really matters in this industry and how to stand out among thousands of people from bootcamps or other pseudo guides on Udemy.
Each question in this course costs you less than 0.5 $. Each of them is an investment in your development and an opportunity for direct contact with me.
Sample questions (answers in the course):
How do you approach creating views in a mobile application intended to run on multiple types of mobile devices?
What is the difference between .svg and .png graphic files in terms of optimization in a mobile application?
Why should custom hook names start with the word "use"?
What are the types of libraries (dependencies) in package.json in React-Native?
What libraries and state management hooks do you know, and when is it worth using them?
Where do you get information about React-Native updates?
What does the course include?
In the course, you get access to 5 tests, each consisting of 20 questions about React-Native. After completing each test, you receive a list of tools and libraries worth knowing at that level to be an attractive candidate in 2024.
You will also receive a link to an Excel file where you can self-assess your level (junior, mid, senior, expert).
Who is it for?
Are you planning to get your first job or switch to a better one? Check what questions you can expect in 2024 and learn the answers expected by recruiters first-hand! Find out which tools and libraries are highly desired in the market and used in commercial projects.
About me
As a React-Native developer, I've worked over 15,000 hours. I also conduct recruitments from juniors to seniors in this technology. Despite increased competition in the market, it's still difficult to find a programmer who can work independently and is attractive to clients. For mid-level positions, I reject 8 out of 10 people after technical interviews, even though recruitment is easier than for juniors! You don't ask mids about theory and basics but about experience and approach to various issues. Still, most of them are not suitable due to lack of knowledge of libraries and tools commonly used in commercial projects and lack of team fit in terms of design patterns.
What score is considered passing in the practical test?
The passing level for each test is 50%. However, take it with a grain of salt because the questions are really difficult and cover many areas of mobile development work. If you want to know how to assess your skill level, search for my article on Google: "junior, mid, senior, or expert – how to classify yourself?"
Can I take the practical test more than once?
You can take each practical test multiple times. After completing the practical test, your final score will be published. With each attempt, the order of questions and answers is randomized, so it's worth repeating them.
Is there a time limit for the practical tests?
Each test consists of 20 questions and has a time limit of 30 minutes. 1.5 minutes per answer in a closed test format is quite sufficient, but consider that in reality, you would need to provide oral answers.
