A while ago, I took Capital One’s CodeSignal assessment. This was a very important opportunity, and I wanted to make sure everything went smoothly. I decided to try using AI coding interview assistants I had seen on TikTok.
I first checked Interview Coder and was immediately shocked by the price. The only option was to pay $899 for lifetime access. But I won’t be interviewing every day all year, and I only needed help for one month. I felt that this high cost was unnecessary. (Linkjob AI starts at just $24.99 per month, which is far cheaper than Interview Coder.)
Still, I tried it to see if it could actually meet my coding interview needs. Unfortunately, after downloading and installing it, I had no idea how to use it because there was no user guide. Clicking a few buttons didn’t trigger any response.
At that time, I was certain that this product wasn’t suitable for me, and I needed to find another AI coding interview assistant. That’s when I discovered Linkjob AI, which covers also the core features that Interview Coder offers. I have now successfully passed my interview, and I’m happy to share my experience using both products.

Interview Coder only offers a one-time payment of $899. It claims that this is equivalent to paying just $25 per month, but I have no idea how that number was calculated. All I saw was that, even though I only needed a one-month membership for my Capital One interview, I still had to pay 18 times more than Linkjob AI’s most expensive plan for similar features.

Linkjob AI, on the other hand, offers multiple pricing options. After downloading it, I tried it out with a friend for about 30 minutes, following the guide to explore all its features. Before subscribing, I compared the available plans:
Free trial | 0$ (10 min + 20 min. Can try all the features of the paid subscription.) |
Annually Plan | 24.99$ / month |
Quarterly Plan | 34.99 / month |
Monthly Plan | 49.99 / month |
I then chose the one that best fit my interview schedule. After subscribing, I was able to use all the features without any limits throughout the subscription period.


First and foremost, my biggest concern was whether using AI during the interview could be detected. On this point, both products claim that the AI cannot be seen by the interviewer. I ended up using Linkjob AI, and the interview went very smoothly, it truly could not be detected.


I also checked in advance which meeting platforms and technical interview platforms the two products support. Both products claim that they cannot be detected under any circumstances on any platform:


Besides the two points above, I also compared some other features that are used in coding interview scenarios:
Features | Linkjob AI | Interview Coder |
|---|---|---|
AI Coding Interview Copilot | Automatic or manual screenshot upload. | Manual screenshot. |
Customized Coding Interview Settings | Can be set up in advance. Can modify it during the interview without being detected. | Must be set up in advance. Modifying it during the interview will be detected. |
Supported Programming Languages for Coding Interviews | Supports various programming languages | Supports 16 programming languages |
AI Answer Panel | Can be retracted and freely dragged around the screen. | Cannot be retracted, and can only be moved to multiple specific positions on the screen using keyboard shortcuts. |
One thing to note is that in Interview Coder, switching programming languages during the interview can be seen on the shared screen. Therefore, I need to choose my language beforehand and cannot change it midway. Otherwise, if I am sharing my screen, the interviewer will notice. The same applies to the output language and the meeting audio language. If my coding interview requires interaction with the interviewer, I need to make sure both are set in advance.


However, if I'm using Linkjob AI, I don’t need to worry about any of these points. Even if I change the AI-generated answer prompt or the meeting language during the interview, the interviewer on their side won’t see it through screen sharing. This makes Linkjob AI very flexible and focused on providing a genuine user experience, allowing me to truly handle the uncertainties that come up in real interviews.

Besides the main features for coding interviews, I also tested and compared these two products in some other areas that I’m particularly concerned about:
When talking with an interviewer, Interview Coder requires me to manually click buttons like “Start Interview,” “Pause,” and “Finish.” If I don’t press them at the right moment, the AI might miss part of the interviewer’s question, leading to incomplete or incorrect answers. There can also be a delay after clicking, which makes managing the AI especially challenging during a high-pressure coding interview.
On the other hand, Linkjob AI can automatically detect sentence breaks and generate responses without any manual intervention. This allows me to fully focus on answering the interviewer’s questions, including follow-ups or technical questions about my code, without being distracted by controlling the AI. However, I noticed that the AI’s sentence break detection isn’t always precise. It sometimes treats two sentences as one, and other times splits a single sentence into two. In those cases, I have to look through the AI’s response history to find the answer. Fortunately, this doesn’t interfere with my overall use.

Interview Coder only asks for my position and years of experience the first time I open the software after installation, and the options are quite limited. For instance, I could only select a broad category such as Software Engineer, 3–5 years, and once chosen, these settings cannot be changed later.
Linkjob AI allows full customization directly via the “Settings” button. I can set prompts to control how the AI answers questions and follow-ups from the interviewer, choose the programming language for coding problems, and structure its explanations. I can also upload my resume and details about the company and position I’m applying for, which helps the AI generate more personalized and relevant responses.
Interview Coder does not specify which AI model it uses to generate responses.
Linkjob AI, however, offers the flexibility to choose from 126 different AI models. This means I can take advantage of the strengths of each model and select the one that best fits my interview needs. For example, if I was preparing for a coding interview, I would choose an AI model that’s strong at programming to help me, such as ChatGPT-5. It should also help answer the interviewer’s questions about my coding process.
Using Linkjob AI was really straightforward. As soon as I downloaded the software, I watched the two-minute intro video and quickly figured out how to use it on my own. Every button responds appropriately when clicked, and their functions are intuitive. The software also mentions that if you ever run into issues, you can reach out to the staff in the group chat anytime.
Interview Coder, however, was a completely different story. It didn’t have any guide, so I was left to figure everything out myself. When I first installed it, I was really confused: clicking “Start Interview” or “Take Screenshot” didn’t seem to work, and the “Take Screenshot” and “Solve Screen” buttons looked almost identical, with no clear difference. I later found a YouTube video introducing it, but it only showed how to download the software and didn’t explain any of the functions. Eventually, I found a video that was nearly 20 minutes long explaining everything, but seeing how long it was, I had already lost interest.
Almost all of Interview Coder’s functions rely on keyboard shortcuts (e.g., Command+H, Command+B, Command+G, etc.). Its web-based dashboard allows me to configure the AI prompt, but I cannot change it during the interview because the interviewer might notice if I open the webpage.
All of Linkjob AI’s functions can be operated with clicks. I can also use keyboard shortcuts for some frequently used features (e.g., Real-Time AI Interview Assistant, Mock Interview, etc.). I can configure the AI prompts directly on my computer, so any changes remain undetectable.
When Interview Coder takes a screenshot of the coding question and generates an answer, it stays pinned on the screen and takes up a lot of space. Its answer panel cannot be collapsed and reopened, which means I have to choose whether the panel covers the interview question or my code. Either way, it interferes with the interview process. The only workaround is to use a keyboard shortcut to tell it that I’m moving to the next question, at which point the previously generated answer disappears. After that, there’s no way to review the previous AI answer, because Interview Coder does not support viewing the chat history in screenshot feature.
Linkjob AI's answer panel can be collapsed, and it also keeps a history, so I can continue asking follow-up questions about previously generated AI answers. This means that if I am unsatisfied with or unclear about the AI’s solution to a coding problem, I can continue asking the AI questions until I start a new conversation.
Both products have a clean and simple interface. However, I noticed that in Interview Coder, moving the interface requires me to hold down the Command key and use the arrow keys to reach specific positions. In contrast, with Linkjob AI, I can drag it freely to any suitable position with my mouse, though sometimes it drifts to the corner of my screen and I have to drag it back.
Linkjob AI generates answers a bit faster, and in addition to providing complete code solutions, it also offers the problem-solving approach. The code can be copied directly.
Interview Coder also provides full code solutions and highlights key parts of the generated answers, but the code cannot be copied directly.
Both offer phone, email, and web chat support. In addition, Linkjob also has a Discord group. After joining, I found 24/7 targeted support, along with real questions and feedback from current users.
Interview Coder states on its website that its target focus is coding interviews and does not cover the general interview market. However, in practice, it can also hear the computer’s system audio, which means it is capable of responding to the interviewer’s general questions as well.
As for Linkjob AI, I have used it in CodeSignal OA interviews, coding interviews, system design interviews, and HM interviews, and it worked very well in all cases. It performs exceptionally across every stage of the interview.
