A while ago, I applied for a SDE position at Microsoft and quickly received a HackerRank test. I was planning to use an AI interview assistant for this online assessment, so I looked into two options: AI Apply and Linkjob AI.
To me, AI Apply feels more like a tool for the application stage rather than the actual interview. Its optimization for real-time assistant use isn't great. For one, it's not undetectable during the test. Second, it can't handle coding problems. And third, it doesn't offer a free trial. After checking its features, I decided to skip it since it didn't meet my needs.
Linkjob AI, on the other hand, is much better because it’s specifically built for interviews. It’s 100% undetectable, can solve coding problems in addition to general conversational questions, and offers a lot of customization settings.
After comparing the two, I felt Linkjob AI was the clear winner, so that’s what I went with.
I’m really grateful that Linkjob AI helped me pass my interview, so I accepted an invitation to do a review of both tools. In the following sections, I’ll break down their undetectability, features, and pricing to show you their strengths and key differences.


First, the main reason I decided to use an AI interview assistant at the time was that both products claimed to be undetectable. This was the most important factor, because getting caught would have been disastrous. Below are the statements from the two products regarding their undetectability:


I also watched a short YouTube video from AI Apply that showcased the use of their AI Copilot. However, I noticed that it only demonstrated the mobile version, not the desktop version, which was completely different from what was shown on the official website. This made me question whether AI Apply could really operate invisibly on a desktop. Can it actually be used on a computer?
I also checked whether these two platforms support the services I would need for my interview, especially HackerRank. It seems that AI Apply’s AI Interview Assistant can only handle general questions and cannot deal with coding interviews. This was one of the reasons I ultimately chose to use Linkjob AI. The platforms they support are as follows:


It can be seen that Linkjob AI not only supports meeting platforms but also online coding assessment platforms. Moreover, it frequently verifies the AI’s undetectability, which gave me a lot of reassurance.
Besides these two most important points, I also looked into the other features and functions of the AI Interview Assistant on both platforms:
Features | Linkjob AI | AI Apply |
|---|---|---|
Undetectable during screen sharing | Supported | Not mentioned |
Not visible in the Docker tray | Supported | Not mentioned |
Undetectable in the active tab | Supported | Not mentioned |
Customized Service | Can upload resume, positions applied for, and companies applied to. Can also add any additional information to provide. | Not mentioned |
General interview questions (e.g., behavioral questions, cultural fit, motivational questions, etc.) | Supported | Supported |
Coding Interview | Supported. Answers include problem-solving approach and complete code solutions. | Not supported |
Screenshot response | Supported | Not supported |
File upload response | Supported | Not supported |
Intelligent Suggestions | After hearing the interviewer’s question, the AI supports immediately choosing a response direction or directly generating an optimal comprehensive answer. | Not supported |
List the key points of the answer in bullet points | Supported | Not supported |
Basically, AI Apply doesn't support undetectability on desktop, which is why they only focus on mobile. As soon as I share my screen or if the platform tracks active tabs, I'll get caught immediately.
In comparison, Linkjob AI takes into account various points where detection could occur and provides clear explanations. It also supports a wider range of interview scenarios and can be used at every stage of the process.



Now, I will compare the subscription plans of the two products. For a better comparison, I have converted AI Apply’s weekly plan into a monthly subscription cost.
Linkjob AI Plans | Linkjob AI Pricing and Supported Functions | AI Apply Interview Buddy Plans | AI Apply Interview Buddy Pricing and Supported Functions |
|---|---|---|---|
Free Trial | $0 (20 minutes) Allows access to all features of the paid subscription during the trial. Doesn't support AI model selection. | Desktop Yearly Plan | 12$ / month Includes AI Interview Prep Tool. Does not include an AI Interview Assistant. |
Annually Plan | 24.99$ / month All features are available without any limits. Free choice of AI models. | Desktop Monthly Plan | 29$ / month Includes AI Interview Prep Tool. Does not include an AI Interview Assistant. |
Quarterly Plan | 34.99$ / month All features are available without any limits. Free choice of AI models. | Mobile Yearly Plan | 9.6$ / month Includes AI Interview Assistant. |
Monthly Plan | 44.99$ / month All features are available without any limits. Free choice of AI models. | Mobile Weekly Plan | 64.95$ / month Includes AI Interview Assistant. |
Since AI Apply’s AI Interview Assistant offers different pricing and services on desktop and mobile, and does not explain the specific differences between them, I can’t be sure if it’ll stay undetected during a real interview. Additionally, AI Apply does not offer a free trial; payment is required to experience any of its services. Below are the screenshots I captured:


AI Apply only supports using ChatGPT-4o or ChatGPT-5 for submitting resumes, and ChatGPT-5 is only available with the Pro Plan subscription. As for the AI Interview Assistant, it does not specify which AI model it uses, nor can users choose one.
Linkjob AI, on the other hand, gives me access to over 120 AI models across all plans. This includes various versions of leading models like ChatGPT, Grok, Llama, Claude, Gemini, and more.
AI Apply does not allow me to adjust the AI prompt.
Linkjob AI allows me to customize the AI prompt, enabling the AI to generate answers that better match real situations. If there are specific roles or answer requirements, the prompt can also be adjusted accordingly.
Below is a comparison of some other services and features offered by the two products:
Features | Linkjob AI | AI Apply |
|---|---|---|
Languages Supported | 52+, and the AI automatically detects them. | 20+. |
Answer generation speed | Ultra-low (in one second) | Generates very fast. |
Automatically recognizes interview questions and generates answers | Supported | Supported |
Live transcription | Supported | Supported |
View AI answer history | Supports viewing all | Can only view the previous topic |
Move answer panel | Supported | Supported |
Collapse answer panel | Supported | Supported |
Technical interviews | Supported | Supported |
Supported programming languages | All major programming languages. | Does not support coding interviews |
AI Apply does not provide official instructions for using the AI Interview Assistant, although there is a one-minute introduction that does not cover its undetectability or how to use its features.
Linkjob AI, on the other hand, has a two-minute YouTube tutorial that explains everything in detail. After watching it, I was able to operate it on my own. Once I downloaded the desktop version, I could also access the tutorial directly within the software. I immediately asked a friend to help me test all the features.
AI Apply only supports email for submitting issues.
Linkjob AI supports email, phone, web chatbot, Discord group chat, and more, providing 24/7 assistance.
AI Apply allows partial refunds. Refunds can be requested for reproducible and verifiable technical issues that seriously affect access or use of paid services. Sufficient and reasonable evidence must be provided.
Linkjob AI supports full refunds, which can be requested through any channel.
AI Apply collects personal information solely to provide its services. This does not apply to publicly available information, independently developed information, or information legally obtained from third parties without confidentiality obligations.
Linkjob AI collects personal information only to provide its services. All data is stored locally, ensuring it never leaves the user’s device.
Absolutely. AI Apply is better for resume optimization and submitting applications, while Linkjob AI’s AI Interview Assistant is more effective for interview preparation. It’s not just for HackerRank tests. I also used Linkjob AI in several later interview stages. I uploaded my resume, applied to companies and positions, and fine-tuned my AI prompts for each stage. The generated answers closely matched my real situation as well as the interviewer’s questions and follow-ups.
No any extra payment is required. The subscription already includes access to the APIs of over 120 AI models, so there are no additional costs.
AI Apply officially states that some users have successfully passed interviews. As for Linkjob AI, after joining its Discord group, I saw many positive reviews from users who had already passed their interviews.
