diving deeper: technical interview questions

Now let’s get into the nitty-gritty. These questions will test your technical knowledge and problem-solving skills. Be prepared to discuss specific technologies, frameworks, and design patterns.

Here are some technical interview questions you might encounter. Remember to explain your thought process clearly.

Question 7

Explain the concept of the dom (document object model).
Answer:
The dom is a programming interface for html and xml documents. It represents the page so that programs can change the document structure, style, and content. The dom represents the document as a tree structure, where each node represents a part of the document (e.g., an element, attribute, or text node).

Question 8

What is the difference between == and === in javascript?
Answer:
== is the equality operator, which compares two values after type coercion (if necessary). === is the strict equality operator, which compares two values without type coercion. It returns true only if the values are of the same type and have the same value.

Question 9

Explain what responsive design is and why it’s important.
Answer:
Responsive design is an approach to web design that aims to make web pages render well on a variety of devices and window or screen sizes. It’s important because it ensures that users have a consistent and optimal experience regardless of the device they’re using.

Question 10

What are some advantages of using a css preprocessor like sass or less?
Answer:
Css preprocessors offer features like variables, nesting, mixins, and functions. These features can help you write more maintainable, reusable, and organized css code. They also allow you to use more advanced features that aren’t available in standard css.

Question 11

Describe your experience with a javascript framework like react, angular, or vue.
Answer:
I have extensive experience with react. I’ve used it to build [mention specific projects or features]. I’m familiar with concepts like components, state management (using redux or context api), and hooks. I also understand the importance of performance optimization and testing in react applications.

Question 12

What are some ways to optimize website performance?
Answer:
Some ways to optimize website performance include: minimizing http requests, compressing images, leveraging browser caching, using a cdn, minifying css and javascript, and optimizing code for faster execution.

Question 13

Explain the concept of asynchronous javascript and how it’s used.
Answer:
Asynchronous javascript allows you to execute code without blocking the main thread. This is important for tasks that take a long time to complete, such as fetching data from an api. Asynchronous operations are typically handled using callbacks, promises, or async/await.

Question 14

What are some common ui design patterns?
Answer:
Some common ui design patterns include: model-view-controller (mvc), model-view-viewmodel (mvvm), and component-based architecture. These patterns help to organize and structure ui code, making it more maintainable and scalable.

Let’s summarize everything that we have learned. Also, add some new questions to enrich the information.

Question 15

How do you handle cross-browser compatibility issues?
Answer:
I typically use tools like browserstack or saucelabs to test my code on different browsers and devices. I also make sure to use css resets and vendor prefixes to ensure consistent rendering across different browsers.

Question 16

What is your approach to testing ui components?
Answer:
I typically use unit tests to test individual components in isolation. I also use integration tests to test how different components interact with each other. I use testing libraries like jest or mocha and enzyme or react testing library for react components.

Question 17

Describe a challenging ui engineering problem you faced and how you solved it.
Answer:
In a previous project, I had to optimize the performance of a complex data table that was rendering slowly. I solved this by implementing virtualization, which only renders the visible rows in the table. This significantly improved the rendering performance and user experience.
