My secret hacks for beating Hackerrank proctoring tools in 2025 and passing every test

As companies are tightening their monitoring of AI tool usage during interviews, it’s no longer possible to simply open ChatGPT and pass like before. However, there are still ways to bypass detection on HackerRank.

I used a product called Linkjob.ai for an interview the other day, and the experience was pretty smooth. They claim it’s completely undetectable. I’ve used it in my online assessment now, and it really held up.

I successfully passed my interview using this tool, and that's why I'd like to share my experience here. I’ll also be revealing a few practical tips on how I used AI during the interview to keep it seamless.

How to Cheat on HackerRank: An Overview of Detection Methods

Track Screen

Many coding interviews require screen sharing, and interviewers often ask how I’m thinking through the problem or how I’d optimize certain parts while I’m coding. This is a tough situation to handle because I have to answer the interviewer’s questions or modify my code on the spot based on the current context. This is exactly when I need AI assistance the most in a live coding interview. However, since I’m sharing my screen, every move I make is visible to the interviewer.

However, Linkjob.ai remains invisible thanks to its system-level integration, which allows the tool to function as an always-on-top overlay. This means I can use it even during screen sharing without being detected. To make sure it was truly hidden, I actually did a test run with a friend before my interview. When I shared my entire screen, the result was as follows:

However, just because it’s invisible on my computer doesn’t mean it will be bug-free on yours. I’d still highly recommend doing a test run with a friend via a video call before your actual interview, just to be safe.

Track Active Tab

Typically, online testing platforms have built-in monitoring for browser activity. On HackerRank, for instance, switching tabs triggers an alert because the platform monitors everything within the browser's sandbox.

However, Linkjob AI operates as a native application outside of the browser's environment. Because it resides on a different system layer, it remains completely invisible to the web-based tracking scripts. This allows me to use AI assistance without ever interacting with the browser's focus or triggering its tab-tracking alarms.

Webcam Proctoring

Recently, interview platforms have been cracking down on AI use. I’ve seen many posts on Glassdoor and Reddit mentioning that online assessments now require cameras to be on, and the same goes for many technical interviews. This means if I’m constantly staring at the AI window on my screen, there’s still a risk of being caught.

However, this is not an unsolvable problem. Based on my experience, here are a few effective strategies:

Adjust Transparency and Overlay: Before the interview, I decrease the opacity of the AI answer panel and position it directly over the problem description. This allows me to read the prompt and the AI suggestions simultaneously. To the interviewer, it simply looks like I am analyzing the problem thoroughly.
Optimize Window Placement: While answering questions, I move the AI answer panel directly below the webcam. This keeps my eye line much more natural. I also make sure to glance at the camera every now and then to keep the connection with the interviewer.

Track Keystrokes / Copy Paste Detection

Online testing platforms track my keyboard strokes and clipboard activity. Frequent Ctrl+C and Ctrl+V actions, or abnormal keyboard input rhythms (such as sudden large-scale code entry after a long period of inactivity), will lead the system to suspect that I'm using external tools for assistance.

However, this problem is also the easiest to solve. I just need to manually type in the code based on the AI-generated answers. The only thing to keep in mind is to control my typing pace, and slow down appropriately on the more difficult parts. Then, I can submit my answers at a reasonable time.

How to Cheat on HackerRank: Bypassing Plagiarism Detection

Delivery & Critical Thinking

Don't just read the AI's response word-for-word. Interviewers aren't stupid. Use the AI for reference, but always include your own thoughts. After all, AI can't truly replicate human intuition.

If the code is too perfect, it lacks personality and risks raising red flags. When coding, try adding some of your own comments.

Coding Habits

In a real coding session, people usually write the main logic first and then handle edge cases or fix bugs during review. If you nail every edge case perfectly right from the start, it looks suspicious. Make sure your coding process follows a natural workflow.

Soft Skills & Realism

Problem-solving shouldn't be instantaneous. Don't just blur out the perfect solution immediately; introduce a few minor "flaws" or a thinking process that doesn't affect the final result.

If you wear glasses, be careful about reflections. The interviewer might be able to see your actual screen in the glare.

AI Tone & Preparation

AI-generated answers can sound unnatural and tend to use overly absolute language, which is a telltale sign. Rephrase those parts so you don't sound overly confident.

At the end of the day, AI is just an assistant. You shouldn't rely on it entirely. Before the interview, you still need to thoroughly review your resume and past projects, and research the company and the role you're applying for.

How to Cheat HackerRank Test Using AI

Next, I’d like to highlight some of the HackerRank AI assistant features I’ve used that make the whole process much more efficient.

Capture Live Screenshot

For me, the screenshot-to-answer feature is easily the most practical tool for HackerRank interviews. I can have Linkjob AI capture the entire screen or just a selected area. If one screenshot isn't enough to cover the whole problem, I’ll take multiple shots. It supports processing up to six images at once, which is a very useful feature for complex problems.

I also pre-set my AI prompts in the settings beforehand. This saves me a lot of time because I don’t have to spend a single second during the actual interview telling the AI what to do once it receives my images. For example, I’ve set my prompt to: "This is my coding problem, please provide the solution logic and the full code answer."

While the tool offers a one-click copy for code answers, I never actually use this feature during an interview. My approach is always to manually type out the code to avoid any risk of copy-paste detection that might suggest I’m using an AI tool.

Attach Images / Upload File

I haven't actually used this feature in an interview yet. I feel like it's more geared toward case studies. I only really consider using AI for technical and behavioral interviews, so this specific function isn't that useful for me.

Streaming Conversation AI Copilot

This feature is incredibly helpful for conversational interviews. For instance, it comes in handy when an interviewer asks a follow-up question during a tech round, or when I need a clearer structure for my thoughts during a behavioral interview.

Linkjob AI can automatically recognize the interviewer’s questions and generate answers. This means I don't have to manually explain the questions to the AI myself.

However, it doesn’t always perfectly catch the cutoff point of a question. For instance, if the interviewer talks too fast or doesn't pause clearly, the AI might lump two separate questions into one. But thankfully, it shows the conversation history in real-time, so I can still get all the answers I need from there.

Personalized Service

To make AI responses more tailored to my real situation, I uploaded my resume, target positions, and companies. Before each interview, I fine-tune my AI prompt to ensure the output matches my tone and background.

By the way, there’s a new version out now. The dashboard offers way more customization options. For example, there are more choices for system prompts, and you can fine-tune the AI responses with much more detail.

FAQ

Can the Linkjob AI icon be hidden from the Dock?

Yes. You can toggle off its visibility in the settings.

Will HackerRank's monitoring system identify "perfect code" as AI-generated answers?

It's very likely. So, as I suggested in the main text, it’s best not to copy the AI’s code verbatim. You can add some comments or even include a few minor flaws that don't affect the overall logic.

Besides HackerRank's OA, can I also use LinkJob AI in other rounds of the interview?

Yes, you can. Linkjob AI can also be used for other interview stages. You can select your preferred prompt in the system prompts beforehand, and if you’re not satisfied with the default options, you can always customize your own.

For example, if you are in a general interview, you can select the "Interview Assistant" prompt. For a technical interview, you can switch to the "Technical Interview Helper" prompt.

An advanced tip is that you can edit the prompt content to include some of your personal background. This makes the AI's answers much more tailored to your specific situation.
