Interviewers are required to be familiar with W3C technical specifications and standards

W3C (World Wide Web Consortium) is an international standards organization dedicated to developing Web technical specifications and standards. In the field of web development, being familiar with W3C's technical specifications and standards is a very important quality, especially when participating in interviews for W3C-related positions.

Being familiar with W3C's technical specifications and standards means that you have a deep understanding and mastery of the basics of web development. These specifications and standards include HTML, CSS, JavaScript and other Web-related technologies. In W3C interviews, interviewers often ask questions about these specifications and standards to assess your technical level.

In the interview, you may face the following questions:

1. Please briefly introduce what W3C is?
   When answering this question, you need to understand the official definition of W3C and the purpose of its establishment. It can be introduced that W3C is a non-profit international standards organization dedicated to promoting and developing Web technical specifications and standards to ensure the interoperability of the Web.
2. Please talk about some new features of HTML5.
   HTML5 is the latest HTML standard developed by W3C, which introduces many new features and improvements. You can mention some new semantic tags (such as

3. In CSS, what do you know about the box model?
   The CSS box model is a model for layout and design defined in the W3C technical specification. You can talk about the difference between the standard box model and the IE box model, and how to use the box model for the layout and design of elements.
4. Please talk about closures in JavaScript.
   Closure is one of the important and interesting concepts in JavaScript. You can explain what a closure is, what it does, and how to use closures.

   HTTP status codes are numeric codes used to represent the status of HTTP requests and responses. 200 means the request was successful, 301 means permanent redirection, and 404 means the resource was not found. You need to understand the meaning of each status code and its application scenarios in web development.

In addition to answering these questions, you can also demonstrate your in-depth understanding and application ability of W3C technical specifications and standards during the interview. For example, you can mention specific cases or technologies that have been applied in actual projects when answering questions.

In short, it is crucial for web developers to be familiar with W3C's technical specifications and standards. Demonstrating your understanding and application of these norms and standards during the interview will help enhance your competitiveness and give the other party a deep impression.
