Pen-Mian Tong AI: An assistant for interview and written tests

What is Penmian Tong?

Bǐmiàn Tōng is an AI-powered tool designed to assist with interviews and written tests; the official website’s home page currently uses the brand name “Yìnjiàn Tōng”.

The official tutorials still make extensive use of the term “PenMianTong”; both names refer to the products and services available under the same domain name.

The main functions of BiMianTong

• Identify issues in real time and generate suggestions for answers.
• Generate personalized content based on the position and resume.
• Import a custom question bank and match it with preset answers.
• It supports recognition and translation in multiple languages, including Chinese and English.
• Handle questions related to technical knowledge, algorithms, and code.
• It offers AI-based eye correction and support for video interviews.
• It supports reviewing interviews and viewing the responses given.
• Websites, desktop clients, and mobile devices work together.

The compliance boundaries that must be understood first

The official website highlights features such as invisibility, protection against screen recording, automatic screenshotting, and real-time answering; these features carry significant regulatory risks.

Using it in formal recruitment, school exams, or qualification tests may violate the rules of the examination venues, platforms, or employers.

• It is primarily used for mock interviews, training, and post-review analysis.
• Before the formal interview, confirm with the organizers whether assistive tools are allowed.
• Do not use real-time answering or invisibility features when there are exam supervision rules in place.
• Do not skip checking screen splitting, screen sharing, and dual-camera functions.
• One must not pretend to have the necessary skills or submit results generated by AI.
• Technical positions require the ability to independently explain code and design decisions.

This article does not provide methods for bypassing exam invigilators, hiding tools, or answering questions on unauthorized tests.

Real-time interview assistance

The product can identify the interviewer’s questions and generate draft responses based on the position, resume, and a database of questions.

Both speech recognition and model responses are affected by accent, noise, the network connection, terminology, and the completeness of the context.

• Job description information helps the model understand the requirements of a position.
• The resume format allows for the inclusion of experiences provided by the user.
• The question bank is used to match common questions related to enterprises and positions.
• The professional recognition engine is designed for conversations that involve many terms.
• Translation skills can assist in mock interviews in a foreign language.
• Review records can be used to identify issues with expression and structure.

How to use the resume mode

In resume mode, the experiences uploaded by the user are extracted to help generate answers to behavioral and project-related questions that are more in line with the individual’s background.

Experiences that AI is not aware of may be filled in or fabricated; therefore, users must ensure that answers refer only to genuine information.

1. Delete the ID number, address, and irrelevant contact information before uploading.
2. Retain positions, projects, responsibilities, outcomes, and time frames.
3. Add target positions and interview rounds.
4. The model is required to use only facts that can be verified from the resume.
5. Check whether the numbers, technology stack, and individual contributions are accurate.
6. Reorganize the final expression in your own words.

Custom question bank

Users can import previous questions, job-related knowledge, and their own prepared answers to improve the relevance of their responses.

Question banks are more suitable as materials for individual review; it is not allowed to upload confidential information from previous employers, disclose exam questions, or include restricted exam content.

• Categorize the questions according to job requirements.
• For each question, prepare facts, actions, results, and reflections.
• Add boundary conditions and make trade-offs for technical issues.
• Mark the policies and industry data that need to be updated.
• Delete unauthorized internal materials.

Tutorial on compliant use of pen and paper

A compliant and effective approach is to use the tool as a question-asking instrument, a feedback source, and an aid for reviewing things before the formal interview.

Pen-and-paper operation procedure

1. Select the target position, level, and company type.
2. Upload a sanitized resume and prepare a personal question bank.
3. Set a full simulation duration of 20 to 40 minutes.
4. Answer independently first, then check the AI’s suggestions.
5. Compare the evidence and logical structure of the two answers.
6. Record the vague, timed-out, and unexplainable parts.
7. Add real cases and remove fictional content.
8. For the second simulation, complete it independently without looking at the answers.
9. Have peers or mentors review the technology and facts.
10. For the formal interview, only the tool rules permitted by the organizing party apply.

Assistance for code and technical interviews

The products cover technical scenarios such as programming problems, algorithmic problems, system design, and the identification of technical terms.

The generated code may contain issues related to complexity, edge cases, security, and language version errors.

• First, explain the approach and the choice of data structure separately.
• Manually review and test each piece of code.
• Analyze time complexity and space complexity.
• Check for null values, duplicate values, and extreme inputs.
• Ensure that each line and the key decisions can be explained.
• Unauthorized AI-generated answers must not be submitted in official evaluations.

AI eye correction

Eye correction adjusts the direction of gaze in the video, making it appear as though the person is looking at the camera.

This feature may alter the appearance of the actual video; it is necessary to verify whether the recruitment platform and the interviewer permit its use before employing it.

• The risk is relatively low when it is used to record practice videos.
• Official AI video evaluations may prohibit image enhancement.
• Excessive correction can result in unnatural facial appearances.
• Genuine expression, active listening, and content quality remain more important.

Which devices are supported?

The official website states that it can be used on PCs, tablets, and smartphones, and provides a web access point that requires no download.

The official tutorial also provides instructions for different operations on Windows, macOS, Android, as well as on smartphones and tablets.

• The web version is suitable for quick access and browsing on the go.
• The desktop client offers more comprehensive local functionality.
• Mobile devices can be used for simulation, viewing, and practice assistance.
• Some modes require coordination between devices.
• Actual compatibility depends on the system, browser, and meeting software.

How are interviews and written tests priced?

Interviews are charged by the hour.

The interview feature consumes points on a per-minute basis, and the cost per minute varies depending on the expert selected, the resume used, the question bank, and the voice engine employed.

• Enabling a resume increases the multiplier for points consumption.
• Each additional question bank also increases the consumption.
• Professional speech recognition engines incur additional charges per minute.
• The longer the interview lasts, the more total points are consumed.

The written test is charged per question.

The written test function consumes points for each question; the cost of each question is determined by both the expert-defined base price and the multiplier applied to that question type.

• The scoring ratios for multiple-choice, multiple-select, short-answer, and essay questions are different.
• The scoring multiplier for programming questions is higher than that for regular multiple-choice questions.
• Additional features such as voice and screenshots increase consumption.
• The actual deduction amount shall be as indicated on the page before starting the task.

Price of the subscription package

As of August 30, 2026, the anonymous website and public tutorials do not display all current payment options in their entirety.

Before making a purchase, log in to check your available points, the discount rate, the validity period, and the estimated amount of points required for that particular task.

• Do not estimate the current price based on old tutorials or third-party websites.
• Packages with a high total price usually have a lower cost per point.
• The refund is not calculated by returning an equivalent amount based on the remaining points.

Remote teaching package

The official tutorial currently offers three levels of remote teaching services, suitable for users who need guidance on how to use the software.

The prices listed above are the official tutorial prices as of August 30, 2026; the actual purchase details and services will be subject to the confirmation provided by customer service.

The tutorial states that once distance teaching takes place, the fee for teaching will not be refunded, even if the software is not used thereafter.

What should be taken into account regarding refund rules?

For refund via points, the amount consumed is first calculated based on the range of points that have been used, and then that amount is deducted from the total payment.

It does not issue a refund in proportion to the remaining balance of points; once a certain amount of usage has been reached, there may be no amount that can be refunded.

• The items included as a gift or at a discount in the premium package are usually not refunded at the premium price.
• For multiple orders, it may be necessary to first deduct the points from previous orders that have already been used up.
• The refund amount is calculated using the official formula and returned to the original source.
• Before making a purchase, keep the order details and the refund policies in place at that time.
• Remote teaching and software points are separate services.

Privacy and resume security

Resumes, question banks, and interview audio may contain a great deal of personal information, contact details, and company-related data.

Before uploading, the principle of doing only what is necessary should be followed, and it is important to understand how the platform handles input data, recordings, and generated records.

• Remove the ID number, address, and unrelated contacts.
• Do not upload your current employer’s trade secrets or customer information.
• Do not save actual leaked questions or confidential information in the question bank.
