HTTP/HTTPS

Understanding HTTP and HTTPS

What is HTTP/HTTPS?

HTTP stands for Hypertext Transfer Protocol. It is the way information is sent over the internet. HTTPS stands for Hypertext Transfer Protocol Secure. It is a safer version of HTTP that protects your data during online communication.

What Does HTTP Do?

When you visit a website, your computer sends a request to the server where that website is stored. The server then uses HTTP to send the web page back to your computer. This process allows you to see and interact with websites.

What Makes HTTPS Different?

HTTPS adds a layer of security to this process. It uses encryption to keep your data safe from hackers. When you see "https://" at the beginning of a website's URL, it means the site is secure, and your information is protected. This is especially important for sites that ask for personal information like passwords or credit card numbers.

Why Are HTTP and HTTPS Important?

Understanding HTTP and HTTPS is crucial for safe internet browsing. Here are a few key reasons:

Data Security: HTTPS protects your data, making it harder for unauthorized users to access it.
Privacy: HTTPS helps keep your online activities private, ensuring that your browsing information stays confidential.
Trustworthiness: Websites with HTTPS are seen as more credible and trustworthy. Users are more likely to share personal information with secure sites.

How to Identify HTTPS Websites

You can easily identify if a website uses HTTPS by looking at the browser's address bar. Here’s what to look for:

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.
