Status Codes

Understanding HTTP Status Codes

HTTP status codes are three-digit numbers sent by a server to tell your web browser how a request was handled. In simple terms, they help you understand what happened when you tried to access a website or a specific page. For example, if you see a 404 status code, it means the page you were looking for couldn't be found.

The Importance of Status Codes

Status codes play a crucial role in web communication. They help you and developers understand if a webpage is loading correctly. Here are the main categories of status codes:

Informational Responses (100-199): These codes indicate that a request was received and is still being processed. They are not commonly seen by users.
Successful Responses (200-299): This category means things are working well. For instance, a 200 status code means your request was successful, and you can view the webpage.
Redirection Messages (300-399): These codes let you know that the page you are trying to access has been moved or redirected to a different location. A common example is the 301 status code, which indicates a permanent redirect.
Client Error Responses (400-499): This group shows that there was an issue with the request you made. A popular status code here is 404, which means the page wasn't found on the server.
Server Error Responses (500-599): These codes indicate that there is a problem on the server side of things. The 500 status code means there was an internal server error, and something went wrong on the server.

Why You Should Learn About Status Codes

Understanding HTTP status codes is important for anyone using the web. By recognizing these codes, you can troubleshoot issues and improve your web experience. For example, if you encounter a 404 error, you can check the URL or navigate to the homepage to find what you're looking for.

Additionally, for those interested in web development or digital marketing, knowing status codes can help you optimize your website. Fixing errors and ensuring smooth navigation will improve user experience and boost your site's search engine ranking.

Why You Should Assess a Candidate’s Knowledge of Status Codes

Assessing a candidate’s knowledge of status codes is important for several reasons. First, understanding status codes is a key part of web development and maintenance. It shows that a candidate can troubleshoot issues effectively and keep websites running smoothly.

Second, knowing how to read and respond to different status codes can help improve user experience. For instance, if a website shows a 404 error, an expert can quickly fix it, so users don’t get frustrated. This helps keep visitors on the site and can increase customer satisfaction.

Third, status codes are essential for search engine optimization (SEO). Search engines use these codes to understand how well a site is functioning. Candidates who are skilled in managing status codes can help improve a website’s ranking in search results, making it easier for users to find.

In summary, assessing a candidate's understanding of status codes ensures that they have the necessary skills to keep your website healthy, improve user experience, and boost your online presence.

How to Assess Candidates on Status Codes

Assessing candidates on their knowledge of status codes can be done effectively through targeted skill tests. Here are two relevant types of assessments that can help you evaluate their understanding:

Multiple-Choice Tests: Use multiple-choice questions to evaluate a candidate's knowledge of different HTTP status codes. Questions can cover what each code means, how to respond to specific errors, and best practices for handling status codes in web development. This format allows you to quickly gauge their understanding and identify any areas that need improvement.
Scenario-Based Assessments: Create practical scenarios where candidates must troubleshoot issues related to status codes. For example, present a situation where a webpage returns a 500 server error or a 301 redirect. Candidates should explain how they would diagnose the problem and what steps they would take to resolve it. This type of assessment showcases their critical thinking skills and practical knowledge.

Using Alooba’s online assessment platform, you can easily create and administer these tests to find candidates who excel in understanding status codes. This not only streamlines the hiring process but also ensures you select an expert who can effectively manage your website's performance and user experience.

How Status Codes Are Used

Status codes are an essential part of web communication, serving as a way for servers to convey important information to browsers and users. Here are some key ways status codes are used:

1. Communicating Request Outcomes

When you visit a website, your browser sends a request to the server. The server then responds with a status code, indicating whether the request was successful or if there was an issue. For example:

A 200 OK status code means the request was successful, and the webpage loads as expected.
A 404 Not Found status code informs the user that the requested page does not exist on the server.

2. Troubleshooting and Debugging

Web developers use status codes to troubleshoot issues. If users report problems accessing a website, developers can check the status codes to determine what's wrong. For instance, if a user consistently sees a 500 Internal Server Error, it signals a server-side problem that needs immediate attention.

3. Redirecting Users

Status codes like 301 Moved Permanently and 302 Found are used for redirecting users from one URL to another. This is crucial for maintaining good user experience and search engine optimization (SEO). By managing redirects properly, businesses can ensure that users reach the correct pages, even if the URL has changed.

4. Enhancing SEO Performance

Search engines rely on status codes to crawl and index websites effectively. A correctly configured status code can help boost a website's SEO ranking. For example, a 301 redirect tells search engines that a page has moved permanently, preserving the ranking and authority of the original page.

5. Informing Users

Status codes can also be used to provide valuable feedback to users. For instance, when a user encounters a 403 Forbidden status code, they understand that they do not have permission to access the requested resource. This transparency helps manage user expectations and improves their overall experience on the site.

By effectively using status codes, businesses can enhance web performance, improve troubleshooting efforts, and achieve better SEO results. Understanding how to implement and respond to these codes is vital for anyone involved in web development or online business.

Our Customers Say

I was at WooliesX (Woolworths) and we used Alooba and it was a highly positive experience. We had a large number of candidates. At WooliesX, previously we were quite dependent on the designed test from the team leads. That was quite a manual process. We realised it would take too much time from us. The time saving is great. Even spending 15 minutes per candidate with a manual test would be huge - hours per week, but with Alooba we just see the numbers immediately.

Shen Liu, Logickube (Principal at Logickube)

We get a high flow of applicants, which leads to potentially longer lead times, causing delays in the pipelines which can lead to missing out on good candidates. Alooba supports both speed and quality. The speed to return to candidates gives us a competitive advantage. Alooba provides a higher level of confidence in the people coming through the pipeline with less time spent interviewing unqualified candidates.

Scott Crowe, Canva (Lead Recruiter - Data)

How can you accurately assess somebody's technical skills, like the same way across the board, right? We had devised a Tableau-based assessment. So it wasn't like a past/fail. It was kind of like, hey, what do they send us? Did they understand the data or the values that they're showing accurate? Where we'd say, hey, here's the credentials to access the data set. And it just wasn't really a scalable way to assess technical - just administering it, all of it was manual, but the whole process sucked!

Cole Brickley, Avicado (Director Data Science & Business Intelligence)

I wouldn't dream of hiring somebody in a technical role without doing that technical assessment because the number of times where I've had candidates either on paper on the CV, say, I'm a SQL expert or in an interview, saying, I'm brilliant at Excel, I'm brilliant at this. And you actually put them in front of a computer, say, do this task. And some people really struggle. So you have to have that technical assessment.
